Employment Based First Preference
EB1B Outstanding Professor or Researcher Green Card
Learn the EB1B requirements for internationally recognized professors and researchers, including the qualifying employer, permanent job offer, three years of experience, six evidentiary criteria and final review of the complete record.
Self Petition?
No. A qualifying U.S. employer must file the I-140 petition.
Permanent Job Offer?
Yes. The offered teaching or research position must satisfy the EB1B rules.
Experience Required?
At least three years of qualifying teaching or research experience.
PERM Required?
No. EB1B does not require labor certification.
What Is the EB1B Outstanding Professor or Researcher Classification?
EB1B is an employment based first preference immigrant classification for certain professors and researchers who are internationally recognized as outstanding in a specific academic area. It is commonly called the “EB1B visa,” although approval of the Form I-140 petition establishes the immigrant classification and does not by itself grant a visa or permanent residence.
Unlike EB1A, EB1B is not a self petition. A qualifying U.S. university, institution of higher education or private employer must file the petition and offer the beneficiary a qualifying permanent teaching or research position. The beneficiary must also have at least three years of teaching or research experience in the academic area.
The beneficiary must submit evidence satisfying at least two of six regulatory criteria. Meeting two criteria, however, does not automatically establish eligibility. USCIS considers the evidence as a whole to determine whether the professor or researcher is internationally recognized as outstanding in the academic field.
EB1B is not limited to tenured professors. A qualifying researcher at a university or eligible private employer may qualify, provided the offered position, employer, experience and international-recognition requirements are all established.
Four Core EB1B Requirements
1
International Recognition
The beneficiary must be recognized internationally as outstanding in a specific academic area. The petition should define the academic field carefully and show recognition beyond the beneficiary’s immediate employer or collaborators.
2
Three Years of Experience
The beneficiary must have at least three years of teaching or research experience in the academic area. Experience gained while pursuing an advanced degree may count only under specific regulatory conditions.
3
Qualifying Permanent Position
The employer must offer a tenured or tenure-track teaching position or a comparable permanent research position. Fixed-term, temporary or training positions require careful review and may not qualify.
4
Qualifying Petitioner
The petition must be filed by a qualifying university, institution of higher education or eligible private employer. Private employers must satisfy additional research-staff and institutional-accomplishment requirements.
Which Employers Can Sponsor an EB1B Petition?
Employer eligibility is a separate legal requirement. A strong researcher does not qualify for EB1B unless the petitioner and offered position also fit the statute and regulations.
Universities and Institutions of Higher Education
A U.S. university or institution of higher education may sponsor a beneficiary for a tenured or tenure-track teaching position or a comparable permanent research position. The petition should document the institution, the department, the position and the permanent nature of the offer.
Qualifying Private Employers
A private employer may sponsor a qualifying researcher for a permanent research position if it employs at least three full-time researchers and has achieved documented accomplishments in an academic field. Evidence may include research staffing, publications, patents, grants, product development, licenses, collaborations, facilities and institutional recognition.
Government and nonprofit research employers require careful analysis. Employer type alone does not establish eligibility. The organization, offered position and statutory framework should be reviewed before selecting EB1B.
What Counts as a Permanent Teaching or Research Position?
For a professor, the offer ordinarily must be for a tenured or tenure-track teaching position. For a researcher, the position must be comparable and permanent. The petition should show that the position is of indefinite or continuing duration and is not merely a temporary appointment, training role or short-term project position.
The title on the offer letter is not controlling. USCIS may examine the contract, appointment terms, funding structure, human-resources classification, employer policies and whether the employment is expected to continue absent good cause. A position funded by a grant is not automatically disqualified, but the employer should be able to explain the continuing nature of the employment.
Positions Often Requiring Careful Review
- Postdoctoral fellow or scholar
- Visiting professor or visiting researcher
- Adjunct or part-time appointment
- Fixed-term research scientist
- Grant-limited appointment
- Training fellowship or residency-type research role
Useful Position Evidence
- Detailed permanent offer letter
- Appointment or employment agreement
- Tenure or promotion policies
- Human-resources classification
- Organizational chart and reporting structure
- Evidence of continuing research needs and funding
The Three-Year Teaching or Research Experience Requirement
The beneficiary must have at least three years of teaching or research experience in the same academic area in which international recognition is claimed. Experience letters should identify the employer or institution, exact dates, full-time or part-time nature of the work, duties, research area and the signer’s basis of knowledge.
Teaching or research completed while pursuing an advanced degree may count only if the beneficiary obtained the degree and the qualifying work meets the regulatory conditions. Teaching must involve full responsibility for the class taught. Research conducted during degree study must have been recognized within the academic field as outstanding.
Do not assume that all graduate research automatically counts. The petition should identify the degree completion, dates, work performed and evidence showing that any claimed pre-degree research received the required recognition.
The Six EB1B Evidentiary Criteria
The beneficiary must provide evidence satisfying at least two criteria. USCIS then evaluates the complete record to determine whether the beneficiary is internationally recognized as outstanding in the academic area.
1. Major Prizes or Awards for Outstanding Achievement
Relevant evidence may include competitive scientific, scholarly or academic awards. The petition should document the award’s criteria, scope, reputation, selection process, number and caliber of candidates, and why it recognizes outstanding achievement rather than routine participation or internal service.
2. Membership in Associations Requiring Outstanding Achievements
The membership must require outstanding achievements for admission. Ordinary professional associations based on occupation, degree, payment of dues or years of experience generally are not enough. The petition should include the governing criteria and evidence of how experts evaluate applicants.
3. Published Material Written by Others About the Beneficiary’s Academic Work
The material should be published in professional publications and concern the beneficiary’s work in the academic field. The petition should identify the author, title, publication, date and context and document the publication’s professional standing. Articles authored by the beneficiary are analyzed under the authorship criterion, not this criterion.
4. Participation as a Judge of the Work of Others
Peer review for scholarly journals, conference review, grant panels, dissertation committees, promotion review and other formal evaluation may qualify. Evidence should show that the beneficiary actually performed the judging and explain the significance of the journal, conference, organization or assignment.
5. Original Scientific or Scholarly Research Contributions
The contribution must be original and meaningful within the academic field. Evidence may include influential research, independent adoption, citations placed in context, patents with documented use, clinical or technical implementation, licensing, standards contributions, policy use, commercialization and detailed testimony from knowledgeable experts. Originality alone is not enough to establish international recognition.
6. Authorship of Scholarly Books or Articles With International Circulation
The beneficiary may submit scholarly books or articles in scholarly journals with international circulation in the academic field. Evidence should establish authorship, the scholarly nature of the work, the journal or publisher, circulation and professional audience. Citation evidence can strengthen the overall case but is not a substitute for documenting the publication itself.
Why Meeting Two Criteria Is Not Automatically Enough
USCIS first determines whether the submitted evidence satisfies at least two regulatory criteria. It then considers the quality and significance of the complete record to decide whether the beneficiary is internationally recognized as outstanding in the academic area. The analysis therefore involves more than counting publications, reviews or criteria.
International Scope
The record should show recognition extending beyond one employer, laboratory or close collaboration network.
Field-Specific Context
Publication rates, citations, authorship conventions and recognition practices vary substantially among academic disciplines.
Independent Recognition
Objective records and detailed independent evidence generally strengthen the claim that the beneficiary is outstanding.
Evidence That Can Strengthen an EB1B Researcher Petition
No single metric controls. The petition should explain what the evidence means within the specific academic field.
Objective Academic Evidence
- Peer-reviewed publications and scholarly books
- Citation records with comparative or field-specific context
- Independent discussion, replication or use of the work
- Completed peer review, grant review and editorial activity
- Competitive academic prizes or selective fellowships
- Patents, licensing, implementation or standards use
- Invited presentations and international collaborations
- Evidence of research adoption by independent institutions
Explanatory and Contextual Evidence
- Detailed independent expert letters
- Evidence identifying the beneficiary’s individual role
- Field norms for publications, citations and authorship
- Journal rankings and international circulation evidence
- Institutional evidence showing the importance of a project
- Documentation of clinical, technical or commercial impact
- Proof that citations concern the beneficiary’s substantive work
- Evidence distinguishing the beneficiary from routine researchers
There is no universal publication or citation minimum. A strong case explains the beneficiary’s actual influence, the norms of the academic field and the independent evidence of international recognition.
Positions That May Be Considered for EB1B
No job title automatically qualifies. Eligibility depends on the actual duties, academic area, international recognition, experience, employer and permanent nature of the offered position.
University Teaching Positions
- Tenured professor
- Tenure-track assistant professor
- Tenure-track associate professor
- Tenure-track full professor
- Professor with substantial research responsibilities

EB1B vs. EB1A vs. EB2 NIW
| Issue | EB1B | EB1A | EB2 NIW |
|---|---|---|---|
| Core standard | International recognition as an outstanding professor or researcher | Extraordinary ability and sustained acclaim | EB2 eligibility plus the national interest waiver test |
| Self petition? | No | Yes | Yes |
| Job offer? | Yes, qualifying permanent teaching or research position | No | No for the waiver petition |
| Experience | At least three years of teaching or research in the academic area | No fixed minimum | Depends on advanced-degree or exceptional-ability basis |
| Criteria | At least two of six, plus overall international recognition | Major award or at least three of ten, plus final merits | Proposed endeavor and three-part waiver analysis |
| Typical use | Qualifying professors and researchers with employer support | Highly acclaimed individuals across multiple fields | Broader option for advanced-degree professionals and persons of exceptional ability |
A researcher may be eligible for more than one classification. The best strategy depends on the evidence, employer, position, immigration status, visa availability, cost and long-term employment plan.
Common EB1B Weaknesses and RFE Issues

- Submitting recommendation letters without detailed supporting facts
- Failing to establish three years of qualifying experience
- Claiming all graduate research as qualifying experience
- Using a temporary or fixed-term position without addressing permanence
- Failing to prove the private employer’s research staff and accomplishments
- Relying mainly on recognition from close collaborators
- Failing to distinguish the beneficiary from competent but routine researchers

Frequently Asked Questions About EB1B
Can I self petition for EB1B?
No. A qualifying U.S. employer must file the EB1B I-140 petition and offer a qualifying permanent teaching or research position.
Do I need a PhD for EB1B?
The classification does not state a universal PhD requirement. In practice, many beneficiaries have doctoral degrees because they are professors or advanced researchers. The central requirements are international recognition, experience, a qualifying employer and a qualifying permanent position.
How many citations are required for EB1B?
There is no fixed citation minimum. Citations should be evaluated in the context of the academic field, publication practices, career stage, independent recognition and significance of the cited work.
Is meeting two EB1B criteria enough?
Not necessarily. Satisfying two criteria is the initial evidentiary threshold. USCIS then evaluates the complete record to determine whether the beneficiary is internationally recognized as outstanding in the academic area.
Can a private company sponsor an EB1B researcher?
Potentially. The private employer must offer a permanent research position, employ at least three full-time researchers and have documented accomplishments in an academic field.
Can a postdoctoral researcher qualify for EB1B?
The beneficiary may have a postdoctoral background, but the offered U.S. position must satisfy the permanent-position requirement. Many postdoctoral appointments are temporary, so the specific offer and employer structure must be reviewed.
Can research completed during my PhD count toward the three years?
Sometimes, but only under specific rules. The degree must have been obtained, and research completed during degree study must have been recognized within the academic field as outstanding. Teaching during degree study must involve full responsibility for the class taught.
Can a software engineer or data scientist qualify for EB1B?
Possibly, when the work is genuinely research in a defined academic field, the employer and permanent position qualify, and the beneficiary is internationally recognized as outstanding. A technology job title by itself does not establish EB1B eligibility.
Can I file EB1B and EB2 NIW petitions?
Yes. They are separate classifications with different petitioners and legal standards. The decision should consider employer support, the strength of each case, cost, timing, visa availability and long-term plans.
Does EB1B require PERM labor certification?
No. EB1B does not require PERM, but the employer, position, experience and international-recognition requirements still must be established.
Does EB1B approval immediately grant permanent residence?
No. Approval of the I-140 establishes the immigrant classification. The beneficiary must still complete adjustment of status or immigrant visa processing, and an immigrant visa must be available.
Can a lawyer guarantee EB1B approval?
No. An attorney can evaluate the employer, position and evidence, identify risk and prepare legal arguments, but cannot guarantee how USCIS will decide the petition.
Official USCIS EB1B Resources
Review the USCIS EB-1 overview and the USCIS Policy Manual chapter on outstanding professors and researchers. Government guidance may change, and eligibility depends on the specific employer, position and evidence.
Request an Evaluation of a Potential EB1B Petition
A meaningful EB1B evaluation examines the beneficiary’s international recognition, academic area and experience together with the employer’s eligibility and the permanent nature of the offered teaching or research position.
