EB-1B Requirements: The Outstanding Professor and Researcher Green Card

To qualify for an EB-1B visa, a person needs at least three years of teaching or research experience, an offer of a permanent or tenure-track position from a U.S. employer, and evidence meeting at least two of six regulatory criteria. Unlike the EB-1A, the EB-1B cannot be self-petitioned; an employer is required to file the petition. However, like the rest of the first preference category, it requires no labor certification.

The EB-1B sits within the broader EB-1 green card category alongside the EB-1A and EB-1C. It is generally narrower than the EB-1A in terms of who is eligible, but for professors and researchers who have made a real mark in their field, it is typically the clearer path.

The Three Core EB-1B Requirements

Every EB-1B case has to establish three things before the evidence criteria even come into play.

1. International recognition as outstanding in a specific academic field. Recognition confined to one institution, one employer, or one country is generally not enough.
2. At least three years of teaching or research experience in the field, documented through detailed letters from current or former employers.
3. A qualifying job offer. The position must be tenured, tenure-track, or a permanent research position, meaning one of indefinite duration with an expectation of continued employment. Temporary, visiting, or short-term roles do not qualify.

What “Outstanding” Really Means: The Six Criteria

Beyond the three core requirements above, an EB-1B petition must include evidence meeting at least two of six regulatory criteria under 8 CFR 204.5(i)(3). Two is the minimum requirement; stronger petitions typically document more than that.

1. Major prizes or awards for outstanding achievement in the applicant’s academic field
2. Membership in associations that require outstanding achievement of their members, as judged by recognized experts
3. Published material about the applicant’s work in professional publications, written by others
4. Participation as a judge of the work of others in the same or a closely related field
5. Original scientific or scholarly research contributions to the applicant’s field
6. Authorship of scholarly books or articles in journals with international circulation

Where these criteria do not fit a particular field, USCIS allows comparable evidence to be submitted instead. But the more important thing to remember is what USCIS is actually measuring at this stage. It is not the prestige of the university making the offer, nor is it the applicant’s raw output. USCIS regulation defines “outstanding” by international impact. A tenured professor with a long publication list can still be denied if their work was not recognized beyond their own institution or country, whereas a researcher whose smaller body of work is cited and used internationally can succeed, even if they are at an earlier stage in their career. 

The Employer’s Central Role

Because the EB-1B does not allow for self-petitioning, the applicant’s employer is the petitioner, and therefore plays a key role in the EB-1B process. The employer has to extend a qualifying permanent or tenure-track offer, and must show the ability to pay the offered wage, typically through an annual report, tax return, or audited financial statement.

One requirement depends on the type of employer. A university or other institution of higher education can petition on the strength of the offer itself. A private employer, by contrast, must also show that it employs at least three full-time researchers and that it (the institution itself) has achieved documented accomplishments in the field. An immigration attorney can confirm whether this additional requirement applies to your specific employer.

How USCIS Weighs the Evidence

Meeting two of the six criteria is only the first step. USCIS applies the same two-step analysis it uses for the EB-1A: first it checks whether the evidence meets the criteria, then it makes a final merits determination, weighing the whole record to decide whether the applicant is genuinely recognized as outstanding on an international level. Meeting two criteria on paper does not guarantee approval if the totality falls short.

That second step, the final merits determination, is currently the subject of litigation that could reshape how USCIS applies it. Because the analysis is shared across the first-preference categories, the same developments that affect the EB-1A apply here; the details are covered in our guide to the EB-1A requirements.

EB-1B vs. EB-1A

The two academic-adjacent first-preference routes are easy to confuse, but the practical difference between them is simple. The EB-1A is for individuals of extraordinary ability across essentially any field, and it can be self-petitioned, with no employer required. The EB-1B is narrower, limited to outstanding professors and researchers, and it always requires an employer to file.

Some people qualify for both, and the choice between them can depend on whether a candidate wants the independence of a self-petition or has an employer ready to sponsor a permanent academic position. Which route fits is something that’s worth reviewing with an immigration attorney.
