EB-1B Visa for Professors and Research Professionals

The EB-1B is an employment-based, first-preference immigrant visa category (classification E12) for professors and researchers who are recognized internationally as outstanding in a specific academic area, have at least three years of teaching or research experience in that area, and hold a qualifying permanent job offer from a U.S. university, institution of higher education, or private research employer. The employer files the petition (Form I-140, Immigrant Petition for Alien Workers), and no labor certification from the Department of Labor is required.

What Is the EB-1B Outstanding Professor or Researcher Green Card?

The Immigration and Nationality Act sets aside the first employment-based preference (EB-1) for "priority workers." The statute divides EB-1 into three subcategories: persons of extraordinary ability (EB-1A), outstanding professors and researchers (EB-1B), and certain multinational executives and managers (EB-1C). EB-1B is the middle subcategory, found at INA 203(b)(1)(B).

Congress designed EB-1B for academics whose work has drawn recognition internationally. The category is aimed at people a U.S. university or research employer wants to hire permanently, such as a professor moving into a tenure-track appointment or a scientist joining a corporate research division.

The key difference from EB-1A is the role of the employer. An EB-1A petitioner can file for themselves without a job offer. An EB-1B beneficiary cannot. The U.S. employer is the petitioner, must sign Form I-140, and must show a genuine offer of a qualifying permanent position. The evidentiary standard also differs: EB-1B requires international recognition as "outstanding" in a specific academic area, while EB-1A requires sustained national or international acclaim placing the person among the small percentage at the very top of the field. USCIS and the courts treat both as demanding standards, but they are not the same test.

Who Qualifies for EB-1B? The Three Core Requirements

The regulation at 8 CFR 204.5(i) sets out what a petition must prove. There are three requirements.

1. International recognition as outstanding in a specific academic area. The statute and regulation require that the beneficiary be "recognized internationally as outstanding" in a specific academic area. The regulation defines "academic field" as a body of specialized knowledge offered for study at an accredited U.S. university or institution of higher education. Neither the statute nor the regulation defines "internationally" by reference to particular countries. USCIS evaluates the geographic reach and the quality of the recognition under the totality of the evidence, after first checking whether the petition documents at least two of the six criteria discussed below. Recognition confined to a single institution, or evidence that does not show the work is known and valued by others in the field outside the beneficiary's immediate circle, is unlikely to carry the standard.

2. At least three years of experience in teaching or research in the academic area. The petition must document three years of teaching or research experience in the field. Experience gained while working toward an advanced degree may count, but only if the degree was actually awarded, and either the beneficiary had full responsibility for the class taught or the research conducted toward the degree has been recognized within the academic field as outstanding. The job title does not decide this. A graduate student who was the instructor of record for a course, with full responsibility for it, can count that teaching once the degree is awarded; a graduate student who graded papers or led discussion sections under a supervising professor cannot, because the "full responsibility" condition is not met. Doctoral research counts only if it is recognized in the field as outstanding. Experience is documented with letters from current or former employers that describe the duties performed and the dates.

3. An offer of a qualifying permanent position. The beneficiary must be coming to the United States to fill one of three types of positions:

• a tenured or tenure-track teaching position at a university or institution of higher education;
• a comparable position at a university or institution of higher education to conduct research; or
• a comparable research position with a department, division, or institute of a private employer, but only if the department, division, or institute employs at least three persons full-time in research activities and has achieved documented accomplishments in an academic field.

The offer is proven with a letter from the prospective U.S. employer. The petition does not require a Department of Labor labor certification, and the employer does not go through PERM recruitment or obtain a prevailing wage determination for the EB-1B petition.

The Six EB-1B Evidentiary Criteria (You Need at Least Two)

The regulation at 8 CFR 204.5(i)(3)(i) lists six types of evidence. A petition must include documentation satisfying at least two of them. Meeting two criteria only opens the door; USCIS then reviews the full record to decide whether the beneficiary is in fact recognized internationally as outstanding.

A few practical points about how these criteria are read:

• The regulation asks whether the beneficiary has met the plain terms of the criterion. USCIS's Policy Manual (Volume 6, Part F, Chapter 3) instructs officers to evaluate at the first step whether the evidence satisfies the regulatory language, and to reserve judgment on whether the evidence proves international recognition for the second step.
• Letters of recommendation are not a criterion on their own. They are supporting evidence, and USCIS gives more weight to letters that explain specific contributions and their impact with detail than to letters that repeat the regulatory language. Letters from independent experts who have not worked with the beneficiary can carry particular weight.
• Citation counts by themselves do not establish a criterion. USCIS looks at how citations compare within the field, whether the work has been applied or built upon, and what independent experts say about it.

Comparable Evidence When a Criterion Does Not Fit

Since a Department of Homeland Security final rule took effect on January 17, 2017, 8 CFR 204.5(i)(3)(ii) has allowed a petitioner to submit comparable evidence when a listed criterion does not readily apply to the beneficiary's occupation. This mirrors the comparable-evidence provision that has long existed for EB-1A.

To use comparable evidence, the petition should explain why a particular criterion does not readily apply to the field, and why the substitute evidence is of comparable significance. The USCIS Policy Manual gives examples. For instance, in some fields presentations at major conferences, or high-impact technical reports, may be argued as comparable to scholarly articles. The 2023 Policy Manual update added examples oriented to science, technology, engineering, and mathematics (STEM) fields, while stating that the examples apply to all academic areas.

Comparable evidence is not a shortcut around weak evidence. If a criterion applies to the field and the beneficiary simply does not meet it, comparable evidence is not available for that criterion.

How USCIS Evaluates an EB-1B Petition: The Two-Step Analysis

USCIS adjudicates EB-1B petitions using the two-step framework the Ninth Circuit described in Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010), which USCIS adopted for both EB-1A and EB-1B and incorporated into the Policy Manual.

Step one: the criteria count. The officer reviews each criterion the petition claims and decides whether the evidence meets the regulatory definition of that criterion. At least two must be satisfied (or comparable evidence accepted in place of a criterion). Officers are instructed not to import the ultimate question of "outstanding" into this step.

Step two: the final merits determination. If at least two criteria are met, the officer considers the totality of the evidence and decides whether the beneficiary is recognized internationally as outstanding in the academic area. This is where the quality of the record matters: how the beneficiary's contributions compare to others in the field, who is saying so, and whether the recognition reaches beyond a single institution or community.

The September 12, 2023 Policy Manual update clarified how officers should approach both steps, listed positive factors officers may consider at the final merits stage, and explained how comparable evidence is weighed. An October 2024 update further clarified what counts as qualifying published material about the beneficiary's work. This two-step approach is current agency practice.

Which Employers Can Sponsor an EB-1B Petition?

Only certain employers can be EB-1B petitioners, and the analysis turns on how the employer and the offered position fit the statutory and regulatory categories.

Universities and institutions of higher education. INA 203(b)(1)(B) and 8 CFR 204.5(i)(3)(iii) refer to a "university or institution of higher education." An employer in this group may sponsor either a tenured or tenure-track teaching position or a comparable permanent research position. Whether a given college, medical school, or academic medical center falls within "institution of higher education" depends on how it is organized and accredited. A medical school that is a unit of a university generally fits; a separately organized hospital or research foundation affiliated with a university may instead need to satisfy the private-employer requirements below. The petition should establish which category applies rather than assume it.

Private employers with a research department, division, or institute. A company, hospital, or nonprofit research organization can sponsor an EB-1B petition for a comparable research position if two conditions are met under 8 CFR 204.5(i)(3)(iii)(C): the department, division, or institute employs at least three persons full-time in research activities, and the employer has achieved documented accomplishments in an academic field. The three-researcher requirement is measured at the level of the qualifying organizational unit, and the regulation does not say whether the beneficiary's own position counts toward the three; the petition should document the unit's research staff clearly and address this point directly. Documentation of accomplishments can include the unit's publication record, patents, grants, and research reports. An employer that performs product development but cannot show accomplishments in an academic field will have difficulty qualifying regardless of headcount.

For every petitioner, the beneficiary must be coming to the United States to fill a qualifying teaching or research position. The statute and regulation do not set a percentage-of-time test, but where a position mixes research with clinical duties, management, or product engineering, USCIS decides as a factual matter whether the offered job is a qualifying research or teaching position. In practice this means the petition should include the position description, an explanation of how the duties are allocated, and evidence that the employer intends to employ the beneficiary in that role. The petition should also show how the position compares to a tenured or tenure-track appointment in terms of permanence.

The employer must also show the ability to pay the offered wage, as required by 8 CFR 204.5(g)(2). The obligation generally runs from the priority date until the beneficiary obtains lawful permanent residence. Universities and established research organizations satisfy this with annual reports, audited financial statements, or, for employers with 100 or more workers, a statement from a financial officer. Smaller private employers should expect to submit tax returns, audited financials, or annual reports.

What Counts as a Permanent Position?

The regulation at 8 CFR 204.5(i)(2) defines "permanent" for EB-1B purposes. A position is permanent if it is either tenured or tenure-track, or if it is for a term of indefinite or unlimited duration where the employee will ordinarily have an expectation of continued employment unless there is good cause for termination.

This definition is a frequent point of dispute in EB-1B cases involving non-faculty appointments. Postdoctoral fellowships, visiting professorships, and research appointments with a fixed end date are, on their face, not permanent. The USCIS Policy Manual (Volume 6, Part F, Chapter 3) addresses research positions supported by grants and directs officers to consider the employer's intent, including whether the employer intends to continue the beneficiary's employment and seek continued funding, in deciding whether the position is of indefinite duration with an expectation of continued employment. Evidence about funding goes to that intent; it does not replace the regulatory definition. A defined-term contract that ends on a stated date, without any expectation of continuation, remains problematic even if the employer hopes to renew the grant.

The employer's letter therefore needs to describe the position accurately against the regulatory definition, and the underlying appointment documents should be consistent with that description.

Benefits of the EB-1B Category

No labor certification. EB-1B petitions do not require PERM labor certification. That removes the prevailing wage determination, the recruitment period, and the Department of Labor adjudication that sponsored EB-2 and EB-3 petitions require. It also removes the risk of a PERM audit or supervised recruitment.

First-preference visa availability. EB-1 receives 28.6 percent of the annual worldwide employment-based immigrant visa allocation under INA 203(b)(1), plus any numbers unused by the fourth and fifth preferences. In the September 2026 Visa Bulletin, EB-1 is current for every chargeability area except India and mainland China. When the category is current for the beneficiary's country of chargeability, Form I-485 can be filed at the same time as the I-140.

Premium processing is available. USCIS designates EB-1B for premium processing, with a 15-business-day commitment to take an action specified in 8 CFR 106.4.

Derivative status for family. The beneficiary's spouse and unmarried children under 21 may apply for permanent residence as derivatives under INA 203(d).

A standard that fits academic careers. The six criteria track what academics do: publish, review, present, receive awards, and get cited. The standard, international recognition as outstanding in a specific academic area, is different from EB-1A's requirement of being among the small percentage at the very top of the field, and some researchers with a qualifying job offer will have records that fit EB-1B better than EB-1A.

Retention of the priority date. Under 8 CFR 204.5(e), once an EB-1B I-140 has been approved, the priority date generally can be carried to a later EB-1, EB-2, or EB-3 petition filed by any employer, unless the approval is revoked for fraud, willful misrepresentation, invalidation of a labor certification, or USCIS error.

EB-1B vs. EB-1A vs. EB-2 NIW: Which Category Fits?

A researcher may qualify for more than one category, and the choice affects who controls the case, what must be proven, and how long the wait is.

Each of the following depends on the individual record:

• A researcher who has a tenure-track offer and a solid publication and citation record, but whose profile does not clearly place them at the very top of the field, may find EB-1B a better fit than EB-1A.
• A researcher who expects to change employers before the green card is approved, or whose employer will not sponsor, may prefer EB-1A or EB-2 NIW because those categories do not depend on a specific job offer.
• Beneficiaries born in India or China face different backlogs in EB-1 versus EB-2, and the relative position of the two categories changes over time. Filing in more than one category is permitted, and the approved petitions can be used to retain the earliest priority date.

The EB-1B Application Process, Step by Step

1. Confirm eligibility and choose the strategy. The employer and beneficiary review the three core requirements, identify which of the six criteria the record supports, and decide whether to file EB-1B alone or alongside another category such as EB-1A or EB-2 NIW.
2. Confirm the position and employer qualify. The employer verifies that the position is tenured, tenure-track, or a comparable permanent research position, that the employer fits the university or private-employer category, and, for a private employer, that the department, division, or institute meets the three-full-time-researcher and documented-accomplishments requirements.
3. Assemble the evidence. Gather publications, citation data with field context, awards and their selection criteria, peer review confirmations, membership documentation, published material about the beneficiary's work, and experience letters covering at least three years. Obtain recommendation letters from independent experts and from collaborators, each addressing specific contributions.
4. Prepare the employer's job offer letter and ability-to-pay evidence. The letter should describe the position, its permanence under 8 CFR 204.5(i)(2), the duties, the salary, and the employer's intent to employ the beneficiary in the position.
5. File Form I-140 with USCIS. The employer signs and files Form I-140, Immigrant Petition for Alien Workers, with the $715 filing fee, the Asylum Program Fee that applies to the employer type, the supporting evidence, and a legal brief explaining how the evidence meets each claimed criterion and the final merits standard. Form I-907, Request for Premium Processing Service, may be filed with the I-140 or later while the petition is pending. Filing the I-140 does not give the beneficiary status, work authorization, or travel permission; the beneficiary continues to rely on their existing nonimmigrant status.
6. Respond to any Request for Evidence (RFE) or Notice of Intent to Deny (NOID). USCIS may issue a request for additional evidence. The response deadline is stated in the notice. If premium processing was requested, the 15-business-day clock stops when the RFE or NOID is issued and a new clock starts when USCIS receives the response.
7. Check immigrant visa availability. Under INA 245(a) and 8 CFR 245.2(a)(2)(i)(B), a beneficiary in the United States may file Form I-485 when an immigrant visa is immediately available. USCIS announces each month whether adjustment applicants may use the Visa Bulletin's Dates for Filing chart or must use the Final Action Dates chart to file. Filing eligibility and approval eligibility are different: even when USCIS permits filing under the Dates for Filing chart, the I-485 cannot be approved until the priority date is current under the Final Action Dates chart. If the category is current, the I-485 can be filed concurrently with the I-140 or while the I-140 is pending.
8. Apply for permanent residence. In the United States, the beneficiary and each derivative family member file Form I-485, Application to Register Permanent Residence or Adjust Status. Under current USCIS filing guidance, applicants who are required to undergo the immigration medical examination must submit a completed Form I-693, Report of Immigration Medical Examination and Vaccination Record, with the I-485, and USCIS may reject an I-485 filed without it; applicants who are exempt from the examination, or who may submit a partial Form I-693 (for example, certain applicants who completed a medical examination abroad), follow the exceptions in the Form I-693 instructions. Applicants may file Form I-765 (work authorization) and Form I-131 (advance parole) at the same time. Outside the United States, after I-140 approval the case is transferred to the National Visa Center and the beneficiary applies for an immigrant visa on Form DS-260 with a consular interview.
9. Biometrics and any interview. USCIS may schedule a biometrics appointment for each adjustment applicant or may notify the applicant that previously collected biometrics will be reused. USCIS may also schedule an interview.
10. Receive the decision. If the I-485 is approved, USCIS issues the Permanent Resident Card. If an immigrant visa is issued abroad, the beneficiary pays the USCIS Immigrant Fee and becomes a permanent resident upon admission to the United States.

Documents Typically Needed for an EB-1B Petition

The list below is a starting point. Each case is different, and the strongest petitions are built around the specific criteria being claimed.

From the employer (petitioner):

• Signed Form I-140 with the EB-1B classification selected (Part 2, outstanding professor or researcher)
• Job offer letter describing the position, its permanent nature, duties, salary, and start date
• Evidence that the employer is a university or institution of higher education, or, for a private employer, evidence that the department, division, or institute employs at least three persons full-time in research and has documented accomplishments in an academic field (publications, patents, grants, research reports)
• Evidence of ability to pay the offered wage (annual report, audited financial statements, federal tax return, or a financial officer's statement where the employer has at least 100 employees)
• Evidence of the employer's organization and legal status, as appropriate

From the beneficiary:

• Curriculum vitae
• Copies of diplomas and, where useful, academic transcripts
• Experience letters from current and former employers documenting at least three years of teaching or research, with dates and duties
• Complete list of publications and copies or first pages of key articles, with journal impact information
• Citation report (for example, from Google Scholar, Web of Science, or Scopus) with an explanation of how the counts compare within the field
• Evidence of awards, including the award criteria, the selecting body, and the pool of eligible candidates
• Membership certificates and association bylaws or admission criteria
• Documentation of peer review, editorial board service, grant panel service, or conference committee service
• Copies of published material written by others about the beneficiary's work, with title, date, author, and translation if not in English
• Evidence of patents, licenses, adoption of the beneficiary's methods, or other real-world use of the research
• Recommendation letters from experts in the field, including independent experts who have not collaborated with the beneficiary
• Copy of passport biographic page and, if in the United States, evidence of current status (Form I-94, approval notices)

For the I-485 stage (if adjusting status in the United States):

• Form I-485 for each applicant, Form I-693 where required, birth certificate, marriage certificate for derivative spouses, passport and I-94 records, and evidence of maintaining lawful status, along with optional Forms I-765 and I-131; Form I-864, Affidavit of Support, if a relative of the applicant filed the petition or owns 5 percent or more of the petitioning entity

EB-1B Filing Fees

Government fees change. The figures below were verified against the USCIS fee schedule (Form G-1055), the Department of State fee page, and the premium processing fee rule as of September 28, 2026. Confirm each figure against the live source before filing.

Additional costs can include the medical examination (set by the civil surgeon or panel physician), translations, credential evaluations, and attorney fees. Whether the employer or the beneficiary pays a given fee is a matter of agreement between them for EB-1B, subject to any institutional policy, because the Department of Labor rule that requires employers to bear PERM costs (20 CFR 656.12(b)) does not apply to a category that does not use labor certification.

EB-1B Processing Time and Timeline

Processing times vary by service center, by workload, and by whether an RFE is issued. USCIS publishes current I-140 processing times for each classification on its processing times tool, and that tool is the only reliable source for a current estimate. Timelines can change without notice.

With premium processing. USCIS commits to take one of the actions listed in 8 CFR 106.4 (approval, denial, RFE, NOID, or referral for investigation) on an EB-1B I-140 within 15 business days of receiving a properly filed Form I-907. The commitment is to act, not necessarily to decide the petition. If USCIS issues an RFE or NOID, the clock stops and a new 15-business-day period begins when USCIS receives the response. Premium processing does not speed up the I-485 or the immigrant visa stage, and it does not change visa availability.

Without premium processing. Check the USCIS processing times tool for the current EB-1B (E12) I-140 estimate at the service center handling the case. This page does not state a figure because the published estimate changes.

The green card stage. For a beneficiary whose priority date is current, the I-485 can be filed with the I-140, and the overall timeline is driven by I-485 processing, biometrics, and any interview. For a beneficiary born in India or mainland China, the I-485 (or consular immigrant visa application) cannot be filed until the Visa Bulletin shows an available date under the chart USCIS designates, and cannot be approved until the priority date is current under the Final Action Dates chart. The wait can add years.

Priority Dates and the Visa Bulletin for EB-1B

The priority date for an EB-1B case is the date USCIS receives the properly filed I-140, as provided in 8 CFR 204.5(d). Because no labor certification is involved, there is no earlier PERM filing date to use.

Each month the Department of State publishes the Visa Bulletin, which lists, for each preference category and country of chargeability, the priority dates for which immigrant visas are available. Two charts appear: "Final Action Dates" and "Dates for Filing." USCIS announces each month which chart adjustment applicants may use to file. The Final Action Dates chart controls when a case can actually be approved.

Country of chargeability is generally the country of birth, not citizenship, under INA 202(b). A beneficiary born in India who holds Canadian citizenship is chargeable to India. Limited exceptions allow cross-chargeability, for example to a spouse's country of birth.

As of the September 2026 Visa Bulletin (the bulletin in effect on September 28, 2026), the EB-1 Final Action Date is July 1, 2023 for applicants born in mainland China and October 15, 2022 for applicants born in India. All other chargeability areas are current. The Department of State has also cautioned that EB-1 for India may become unavailable before the end of the fiscal year on September 30, 2026. These dates move month to month, and they have moved backward (retrogressed) as well as forward. Anyone planning around EB-1B should read the bulletin for the current month and not rely on a date from a prior month.

Spouses and Children of EB-1B Beneficiaries

Under INA 203(d), the spouse and unmarried children under 21 of an EB-1B principal beneficiary are entitled to the same preference classification and the same priority date if accompanying or following to join. Their classifications are E16 (spouse) and E17 (child).

Derivatives do not need to be named on the I-140. They file their own Form I-485 (in the United States) or Form DS-260 (abroad), and each must be independently admissible.

A child who turns 21 before obtaining permanent residence may lose derivative eligibility unless protected by the Child Status Protection Act (INA 203(h)). The CSPA formula subtracts the time the I-140 was pending from the child's age on the date an immigrant visa became available, and requires the child to seek to acquire permanent residence within one year of that availability. Under current USCIS policy (Policy Manual Volume 7, Part A, Chapter 7), a visa is considered available for CSPA purposes when the priority date is current under the Department of State's Final Action Dates chart, not merely under the Dates for Filing chart, and the petition must also have been approved. USCIS has changed the chart it uses for this calculation more than once, and the policy includes transition rules that depend on when the visa became available and when the child sought to acquire residence. The calculation is technical, and families with children approaching 21 should have it done before filing and re-checked when the priority date becomes current.

Risks, Traps, and Edge Cases in EB-1B Cases

How Withdrawal, Revocation, Priority Date Retention, and Portability Fit Together

Four rules interact whenever the employment relationship changes, and they are easier to apply when read together.

1. The job offer must be genuine at filing and remain so through approval of the green card, unless portability applies. If the employer withdraws the offer or the position is eliminated while the I-140 is pending, the petition can be denied. If the I-140 has been approved, the employer may still withdraw it. The legal effect of a withdrawal depends on timing: under 8 CFR 205.1(a)(3)(iii)(C), a withdrawal received by USCIS 180 days or more after approval, or 180 days or more after an associated Form I-485 was filed, does not automatically revoke the petition. Even then, the original employer's job offer no longer supports adjustment, so the beneficiary needs either INA 204(j) portability or a new petition to complete the process.
2. Priority date retention (8 CFR 204.5(e)). Once an I-140 is approved, the beneficiary generally keeps the priority date for any later EB-1, EB-2, or EB-3 petition filed by any employer, unless the approval is revoked for fraud, willful misrepresentation, invalidation of a labor certification, or USCIS error. Retention of the priority date is separate from using the original I-140 as the basis for adjustment.
3. Portability (INA 204(j); 8 CFR 245.25). A beneficiary may change to a new job in the same or a similar occupational classification, with the same or a different employer, if the Form I-485 has been pending 180 days or more and the I-140 is approved or is later determined to have been approvable when filed. The new job need not be a tenured or tenure-track position, but it must be same or similar. Form I-485 Supplement J documents the new offer.
4. Before 180 days of I-485 pendency. If the beneficiary leaves the petitioning employer before the I-485 has been pending 180 days, portability is not available. Whether the case can still proceed depends on whether the original employer continues to offer the qualifying permanent job in good faith. The regulations do not require the beneficiary to be working for the petitioner before approval, but the offer must remain bona fide. If it does not, the beneficiary needs a new petition, and the retained priority date (rule 2) can be carried to it.

Other Risks

Postdoc and fixed-term appointments. As discussed above, positions with a defined end date are hard to characterize as permanent. A petition built on a postdoc offer without language about indefinite duration and continued employment is at risk of denial on this point alone.

Counting the three years. Doctoral research counts only if the degree was awarded and the research is recognized in the field as outstanding, or the beneficiary had full responsibility for the class taught. Petitions that count graduate teaching semesters toward the three years without meeting these conditions invite an RFE or denial.

Thin criteria. Meeting two criteria on paper does not carry the case. If the two criteria are, for example, a handful of peer reviews and a modest publication list, the final merits determination can go against the beneficiary. USCIS's Policy Manual states that officers consider the record as a whole and may weigh factors such as the significance of the venue, the extent of independent recognition, and the applicability of the work.

Letters that repeat the regulation. Recommendation letters that assert the beneficiary is "internationally recognized as outstanding" without explaining what the beneficiary did and why it matters add little. Officers are instructed to look for specific, detailed explanations of contributions and their impact.

Status, authorized stay, and work authorization. Filing or approval of an I-140 does not confer status or work authorization. To be eligible for Adjustment of Status, a beneficiary must generally be in lawful status when the I-485 is filed and must not have violated status or worked without authorization, subject to the exceptions in INA 245(c) and 245(k). Once the I-485 is pending, the applicant is in a period of authorized stay, but that is not the same as holding nonimmigrant status. Employment after filing requires either continued valid work-authorized nonimmigrant status (such as H-1B or O-1) or an Employment Authorization Document issued on Form I-765 under category (c)(9). J-1 exchange visitors subject to the two-year home residency requirement under INA 212(e) cannot adjust status until the requirement is satisfied or waived. H-1B holders whose I-140 has been approved may qualify for extensions beyond the six-year limit under AC21 section 104(c) if a visa number is not available because of per-country limits.

Departure and unlawful presence. Adjustment applicants and consular applicants are both subject to the grounds of inadmissibility. The procedural consequences differ. A beneficiary who has accrued more than 180 days of unlawful presence and then departs the United States triggers a three-year bar under INA 212(a)(9)(B)(i)(I), and more than one year of unlawful presence triggers a ten-year bar under INA 212(a)(9)(B)(i)(II). Those bars are enforced at the consulate. A beneficiary with any period of unlawful presence, a prior status violation, or a possible misrepresentation issue should have adjustment eligibility under INA 245 and consular admissibility analyzed separately before choosing between the two paths or traveling.

Public charge and Form I-864. Employment-based adjustment applicants are subject to the public charge ground of inadmissibility under INA 212(a)(4), which USCIS applies under a totality-of-the-circumstances test considering age, health, family status, assets, resources, financial status, education, and skills. In addition, under INA 213A(f)(4) and 8 CFR 213a.2, an employment-based applicant must file Form I-864, Affidavit of Support, if a relative filed the I-140 or if a relative owns 5 percent or more of the petitioning entity. Applicants with criminal history, prior immigration violations, or health-related grounds should have those reviewed before filing.

Concurrent filing when the date later retrogresses. If an I-485 is filed while the priority date is available under the designated chart and the Visa Bulletin later retrogresses past the priority date, the I-485 remains pending but cannot be approved until the date becomes current again under the Final Action Dates chart. While it is pending, the applicant may remain eligible to apply for renewal of the Employment Authorization Document and advance parole, subject to the applicable requirements and USCIS adjudication of each application; renewal is not automatic.

Frequently Asked Questions About EB-1B Green Card

• Can I self-petition for EB-1B?
  No. Under 8 CFR 204.5(i)(1), an EB-1B petition must be filed by a U.S. employer. Researchers who want to control their own case should consider EB-1A or EB-2 National Interest Waiver, both of which permit self-petitioning.
• Does a postdoctoral position qualify as a permanent research position?
  It depends on how the appointment is structured. The regulation requires a tenured, tenure-track, or indefinite-duration position with an expectation of continued employment absent good cause for termination. A postdoc with a fixed end date and no expectation of continuation generally does not meet that definition. Evidence that the employer intends to continue the beneficiary's employment and to seek continued funding can support a finding that the position is of indefinite duration, but the appointment documents need to be consistent with that intent, and eligibility must exist when the I-140 is filed.
• How many citations do I need for EB-1B?
  There is no citation threshold in the statute, regulation, or Policy Manual. USCIS evaluates citations in context: the norms of the field, whether the work has been built upon by others, and what independent experts say about its significance. A researcher in a small subfield with modest absolute counts can still show international recognition, and a high count in a large field does not by itself prove the standard.
• Do I need a PhD to qualify for EB-1B?
  The regulation does not require a specific degree. It requires three years of teaching or research experience in the academic area and international recognition as outstanding. Where the beneficiary relies on experience gained during graduate study, the degree must have been awarded and the research must be recognized as outstanding, or the beneficiary must have had full responsibility for the class taught.
• Do I have to already work for the employer that files the EB-1B petition?
  No. The regulation requires an offer of employment from a prospective U.S. employer, documented by a letter, not current employment. A beneficiary abroad, or one working for a different employer in the United States, can be the beneficiary of an EB-1B petition. The petitioner must, however, intend to employ the beneficiary in the qualifying position once permanent residence is granted, and the offer must remain genuine through the process unless INA 204(j) portability applies.
• Can a company sponsor an EB-1B petition, or only a university?
  A private employer can sponsor an EB-1B petition for a comparable research position if its department, division, or institute employs at least three persons full-time in research activities and has documented accomplishments in an academic field. Universities and institutions of higher education can sponsor either teaching or research positions. Whether a hospital, medical school, or research foundation is an "institution of higher education" or a private employer depends on how it is organized.
• What happens to my EB-1B if I change jobs?
  It depends on timing and on what the original employer does. If your Form I-485 has been pending 180 days or more and the I-140 is approved (or is later found approvable when filed), you may move to a same or similar job under INA 204(j) using Form I-485 Supplement J. If you leave before 180 days, portability is unavailable; the original I-140 can continue to support your case only if the petitioning employer keeps the qualifying permanent job offer open in good faith. Otherwise you need a new petition, and under 8 CFR 204.5(e) you generally keep the priority date from the approved I-140 for that new petition.
• What happens if my employer is acquired or merges with another organization?
  A successor employer may be able to rely on the original I-140 if it establishes that it is a "successor in interest," meaning it has assumed the predecessor's interests and obligations related to the petition and the job opportunity remains the same. USCIS evaluates this on the facts, including the transfer of assets and liabilities. If successor status cannot be shown, the new entity needs its own petition, and the priority date generally is retained. Because the analysis is fact-specific, the affected employer should review it with counsel before assuming the original petition survives.
• Is premium processing available for EB-1B?
  Yes. USCIS accepts Form I-907 for EB-1B I-140 petitions and commits to take one of the actions listed in 8 CFR 106.4 within 15 business days. The fee is $2,965 for requests postmarked on or after March 1, 2026. Premium processing does not speed the I-485 stage or change visa availability.
• Can I file EB-1B and EB-1A or EB-2 NIW at the same time?
  Yes. Nothing prohibits filing more than one I-140 in different categories, and the approvals can be used to retain the earliest priority date. Employers and beneficiaries weigh the cost against the benefit of a second path, particularly where one category has a backlog for the beneficiary's country of chargeability.
• How long after I-140 approval do I get the green card?
  There is no fixed period. If your priority date is current on the Visa Bulletin, you may already have filed Form I-485 concurrently, and the remaining time is I-485 processing as shown on the USCIS processing times tool. If your country of chargeability is backlogged for EB-1, you wait until the Visa Bulletin reaches your priority date before you can file (under the chart USCIS designates) and before your case can be approved (under the Final Action Dates chart).
• Can an approved EB-1B I-140 help me extend H-1B status beyond six years?
  It can, in one situation. Under section 104(c) of the American Competitiveness in the Twenty-first Century Act (AC21) and 8 CFR 214.2(h)(13)(iii)(E), an H-1B worker who is the beneficiary of an approved I-140 may receive H-1B extensions in three-year increments beyond the six-year limit if an immigrant visa is not available because of per-country limits. A separate one-year extension provision under AC21 section 106(a) applies when 365 days or more have passed since a labor certification or I-140 was filed. An approved EB-1B petition alone does not extend H-1B status; the employer must file the H-1B extension petition.
• Does the employer have to pay the EB-1B fees?
  The employer is the petitioner and is responsible for filing Form I-140, but the Department of Labor rule requiring employers to pay labor certification costs (20 CFR 656.12(b)) does not apply because EB-1B does not use labor certification. Who pays the I-140, premium processing, and adjustment fees is a matter of agreement and institutional policy. Employers should confirm any internal or state-law limits with counsel.
• Can my spouse work while our EB-1B adjustment is pending?
  A derivative spouse who has filed Form I-485 may apply for employment authorization on Form I-765 under category (c)(9) and may work once the Employment Authorization Document is issued. Spouses in certain nonimmigrant statuses may have independent work authorization as well.
• What is the difference between "outstanding" and "extraordinary ability"?
  EB-1B requires international recognition as outstanding in a specific academic area, shown through at least two of six criteria. EB-1A requires sustained national or international acclaim placing the person among the small percentage at the very top of the field, shown through a major internationally recognized award or at least three of ten criteria. Both use the two-step Kazarian analysis, and the final merits determination in each case turns on the record as a whole.
