Short answer: The EB-1B green card is an employer-sponsored category for professors and researchers who are recognized internationally as outstanding in a specific academic area. It requires at least three years of teaching or research experience, a qualifying permanent job offer, and evidence satisfying at least two of six regulatory criteria.
Labor certification is not required. However, the absence of PERM does not turn EB-1B into a self-petition. A U.S. employer files Form I-140. The EB-1B service page places the candidate’s evidence and the offered position in the same review.

EB-1B green card quick overview
| Question | Short answer |
|---|---|
| Who files? | A U.S. employer files the I-140 petition. |
| Is PERM required? | No. 8 CFR 204.5(i) expressly waives labor certification. |
| What experience is required? | At least three years in teaching or research in the academic area. |
| How many recognition criteria? | At least two of the six listed criteria. |
| Can a private company sponsor? | Yes, if its research unit meets additional conditions. |
Who qualifies for an EB-1B green card?
8 U.S.C. 1153(b)(1)(B) sets out three conditions. The person must be recognized internationally as outstanding in a specific academic area. The person must have at least three years of teaching or research experience in that area. Finally, the person must seek to enter for a position described by the statute.
That position may be tenured or tenure-track teaching at a university. A comparable university research position may also qualify. A private employer may offer a comparable research position in a qualifying department, division, or institute, subject to additional institutional rules.
EB-1B requires employer sponsorship. That feature separates it from EB-1A, which permits self-petitioning. The article comparing EB-1A and EB-2 NIW explains two other structures that do not depend on the same permanent job offer.
What are the three core EB-1B green card requirements?
| Requirement | Legal source | What the evidence must show |
|---|---|---|
| International recognition | 8 U.S.C. 1153(b)(1)(B) and 8 CFR 204.5(i) | At least two criteria tied to outstanding recognition |
| Three years of experience | Statute and regulation | Teaching or research duties in the academic area |
| Qualifying permanent offer | 8 CFR 204.5(i) | Tenured, tenure-track, or defined permanent research work |
Evidence should not be presented as labels alone. An award must be connected to outstanding achievement in the field. Published material must actually concern the candidate’s work. An experience letter should describe duties instead of repeating a job title.
How do the six EB-1B green card criteria work?
8 CFR 204.5(i) identifies six forms of evidence. At least two must be satisfied. When the criteria do not readily apply, comparable evidence may be submitted.
| Criterion | Relevant record | Common confusion |
|---|---|---|
| Major prize or award | Recognition for outstanding achievement | Participation certificates are not automatically major awards |
| Selective membership | Association requiring outstanding achievement | Fee-based membership alone does not establish selectivity |
| Published material about the person | Work written by others, with identifying details | The candidate’s own article is not this criterion |
| Judging | Review of others’ work in the same or allied field | An invitation should be distinguished from completed review |
| Original contribution | Scientific or scholarly contribution | Originality should be connected to its significance |
| Authorship | Books or articles in journals with international circulation | Authorship must be placed in its field context |
These criteria should not be treated as though they make EB-1B identical to EB-1A extraordinary ability. This article does not claim that the Kazarian framework applies to EB-1B in an identical manner.
When does doctoral work count toward three years?
The regulation allows teaching or research performed while working toward an advanced degree to count only under stated conditions. The degree must have been acquired. Teaching responsibilities must have been full. For research, the doctoral research must have been recognized as outstanding in the academic field.
Experience is documented through letters from current or former employers. A letter should include the author’s name, address, and title and give a specific description of the candidate’s duties. A sentence saying only that the person “conducted research” does not provide the regulatory detail.
Can a private-company researcher use EB-1B?
Yes. The private employer’s department, division, or institute must employ at least three people full time in research activities and have documented accomplishments in the academic field. The offered role must also be a comparable permanent research position.
The inquiry focuses on the relevant research unit, not merely the company’s overall size. Its researchers and documented accomplishments should be shown separately. The offer letter should also describe how the position performs research in the stated academic area.
What does a permanent research position mean?
The regulation defines permanent research employment as tenured, tenure-track, or for an indefinite or unlimited duration with an expectation of continued employment absent good cause for termination. The answer therefore cannot be taken from the job title alone.
A document with a stated term does not necessarily answer every question about the underlying position. The actual structure and expectation of continuity must be examined. The employer’s letter should describe those features clearly and consistently.
How does EB-1B differ from EB-1A and EB-2 NIW?
EB-1B focuses on outstanding professors and researchers and requires U.S. employer sponsorship. EB-1A has a different structure and permits self-petitioning. EB-2 NIW seeks a waiver of the job-offer and labor-certification requirements based on national interest.
No category is universally preferable. The academic field, recognition evidence, offered position, and proposed work must be assessed together. Another employer-sponsored but PERM-free category, EB-1C, applies different rules for managers and executives.
Why does EB-1B not require PERM?
8 CFR 204.5(i) states that labor certification is not required for this classification. That rule does not remove the employer’s obligation to file the petition or prove a qualifying permanent position.
The absence of PERM distinguishes this structure from developments affecting the PERM process. Nevertheless, the EB-1B recognition, experience, and position requirements remain fully applicable.
Common EB-1B green card mistakes
- Treating EB-1B as a self-petition category
- Confusing authorship with published material about the candidate
- Counting all doctoral research automatically
- Ignoring the private research unit’s additional requirements
- Explaining permanence only through a job title
EB-1B green card short checklist
- Define the academic area consistently.
- Separate the supporting record for each claimed criterion.
- Match three years of experience to detailed employer letters.
- Explain the permanent character of the offer.
- If the employer is private, document the research unit’s additional conditions.
Frequently asked questions
Is an employer required for EB-1B?
Yes. A U.S. employer files the petition. EB-1B does not permit the candidate to self-petition.
Does meeting two criteria guarantee approval?
No. All statutory and regulatory conditions are reviewed, and the evidence must genuinely satisfy the claimed criteria.
Can doctoral research count toward the three years?
It may count if the degree was acquired and the doctoral research was recognized as outstanding in the academic field. Proper experience evidence is still required.
Must a private employer offer a professor position?
No. The private-employer provision concerns a qualifying permanent research role in an eligible research unit.
How long does EB-1B take?
The verified sources for this article do not establish a processing time. We therefore do not provide a timeline or predict an outcome.
Conclusion: build the category and position together
EB-1B examines the employer and position along with the candidate’s recognition. International standing, experience, and the permanent offer should form one coherent record. The city of the research position does not change that legal analysis; for the practical side of relocating, see our guide for Turkish residents in Boston.
