EB-1B, the outstanding professor and researcher category, is employer-sponsored: "Any United States employer desiring and intending to employ a professor or researcher who is outstanding in an academic field" may file the I-140 (8 CFR 204.5(i)(1), 2025 edition). No labor certification is needed, but the petition must include a qualifying offer of employment (8 CFR 204.5(i)(3)(iv)).
As of October 23, 2026, many EB-1B cases are won or lost on the employer side: whether the job is "permanent," and for industry research groups, whether the unit meets the three-researcher rule. This guide covers those requirements. Our guide to EB-1B for outstanding professors and researchers covers the researcher's own evidence.
- An EB-1B petition needs an offer letter from a US employer for a tenured or tenure-track teaching position or a permanent research position in the academic field.
- Permanent means tenured, tenure-track, or of indefinite or unlimited duration with an ordinary expectation of continued employment.
- A private employer's department, division or institute must employ at least three persons full-time in research and have documented accomplishments in an academic field.
- Government agencies generally do not qualify unless they are a US university or institution of higher learning.
- Yearly grant-funded contracts can count as permanent if the employer shows intent to seek funding and a reasonable expectation of renewal.
- Temporary, adjunct and limited-duration fellowship positions are not tenured or tenure-track.
- The employer must show the ability to pay the offered salary.
What job offer does an EB-1B petition need?
The regulation requires an offer letter from one of three sources (8 CFR 204.5(i)(3)(iv)):
| Employer | Qualifying position |
|---|---|
| US university or institution of higher learning | Tenured or tenure-track teaching position in the academic field |
| US university or institution of higher learning | Permanent research position in the academic field |
| Department, division or institute of a private employer | Permanent research position, if the unit has at least three full-time researchers and documented accomplishments |
The USCIS Policy Manual adds that the letter must state that the employer is offering "employment in a tenured or tenure-track teaching position or a permanent research position in the beneficiary's academic field," and that the petitioner "must demonstrate that it has the ability to pay the beneficiary's salary" (USCIS Policy Manual, Vol. 6, Part F, Ch. 3).
What makes a research position "permanent"?
The regulation defines it. Permanent, for a research position, means "either tenured, tenure-track, or for a term of indefinite or unlimited duration, and in which the employee will ordinarily have an expectation of continued employment unless there is good cause for termination" (8 CFR 204.5(i)(2)).
The Policy Manual softens two common worries (USCIS Policy Manual, Vol. 6, Part F, Ch. 3):
- No magic clause. Officers "should not deny a petition" solely because the contract lacks a "good cause for termination" clause, though the employer must still show the job is intended to be of indefinite duration.
- Grant-funded jobs. Many research positions are funded by yearly grants. If the employer shows "the intent to continue to seek funding and a reasonable expectation that funding will continue (such as demonstrated prior renewals for extended long-term research projects)," the position can be permanent.
Officers also look at "the circumstances surrounding the job offer as well as the benefits attached to the position" (same).
What about professors' positions?
Tenure status is judged on its own terms. The Policy Manual says the permanence definition "applies only to research positions," and officers need not look for a good cause clause in a tenured or tenure-track contract (USCIS Policy Manual, Vol. 6, Part F, Ch. 3). But it draws a line: USCIS does not consider "positions that are temporary, adjunct, limited duration fellowships, or similar positions where the employee has no reasonable expectation of long-term employment with the university, to be tenured or tenure-track positions" (same).
How narrowly can the academic field be defined?
Narrowly, but not too narrowly. The regulation defines an academic field as "a body of specialized knowledge offered for study at an accredited United States university or institution of higher education" (8 CFR 204.5(i)(2)). The Policy Manual says that body of knowledge "is larger than a very small area of specialization in which only a single course is taught," and gives the example that it would be acceptable to find someone outstanding "in particle physics rather than physics in general" (USCIS Policy Manual, Vol. 6, Part F, Ch. 3). The offer letter, the evidence and the field named in the petition should all line up; our guide to defining the field of endeavor covers the same issue for EB-1A.
Can a private company's research lab sponsor EB-1B?
Yes, if the unit qualifies. The private employer's "department, division, or institute must demonstrate that it employs at least three persons full-time in research positions, and that it has achieved documented accomplishments in an academic field" (8 CFR 204.5(i)(3)(iv)(C)). The test applies to the department, division or institute, not the whole company.
- An organizational chart and roster showing at least three full-time researchers in the unit.
- The unit's documented accomplishments, such as peer-reviewed publications, patents or recognized research results.
- An offer letter describing a permanent research role in the beneficiary's academic field.
- Financial evidence of the ability to pay the salary.
Can government agencies or labs file EB-1B?
Generally not. The Policy Manual says "positions with government agencies at the federal, state, or local level do not fit within the statutory framework unless the government agency is shown to be a U.S. university or an institution of higher learning," and "government agencies do not qualify as private employers" (USCIS Policy Manual, Vol. 6, Part F, Ch. 3). It points such agencies to other categories, such as extraordinary ability, where the researcher qualifies (same).
What does the researcher need beyond the offer?
International recognition and experience. The beneficiary must show at least two of six criteria, such as major awards, memberships requiring outstanding achievement, published material about their work, judging, original research contributions or scholarly authorship (8 CFR 204.5(i)(3)(i)), followed by a final merits determination (USCIS Policy Manual, Vol. 6, Part F, Ch. 3). They also need at least three years of teaching or research in the field; work done while earning an advanced degree counts only if the degree was obtained and the teaching carried full responsibility for the class or the research was recognized as outstanding (8 CFR 204.5(i)(3)(iii)). Our guide to EB-1A for postdocs and early-career researchers compares the self-petition route.
What this means for you
If you are a researcher, the employer's paperwork can matter as much as your citations.
- Ask HR whether the offer can state a permanent, indefinite or tenure-track position in your academic field.
- For grant-funded roles, gather evidence of past renewals and the employer's plans to keep seeking funding.
- In industry, confirm that your unit has at least three full-time researchers and a record of documented accomplishments.
- If you work for a government lab, look at EB-1A or an NIW instead.

Frequently asked questions
What kind of job offer does EB-1B require?
A written offer from the prospective US employer for a tenured or tenure-track teaching position, or a permanent research position, in the beneficiary's academic field. The regulation defines permanent as tenured, tenure-track, or for a term of indefinite or unlimited duration, with an ordinary expectation of continued employment unless there is good cause for termination. The employer must also show it can pay the salary.
Can a tech company sponsor an EB-1B?
Yes, through a qualifying research unit. The regulation allows a department, division or institute of a private employer to offer a permanent research position if it employs at least three persons full-time in research positions and has achieved documented accomplishments in an academic field. Corporate AI, biotech and engineering research groups can fit, but the petition must document both points.
Does a one-year grant-funded research contract count as permanent?
It can. The USCIS Policy Manual says many research positions are funded by yearly grants, and that if the employer shows the intent to continue seeking funding and a reasonable expectation that funding will continue, such as prior renewals for long-term projects, the job can be considered permanent. The employer must still show the position is intended to be of indefinite duration.
Can a government lab file an EB-1B?
Generally not. The Policy Manual says positions with federal, state or local government agencies generally do not fit the EB-1B framework unless the agency is shown to be a US university or institution of higher learning, and that government agencies do not qualify as private employers. It suggests such agencies may use other categories, such as EB-1A, where the researcher qualifies.
Does a postdoc position qualify for EB-1B?
Usually not as the offered position, if it is a fixed-term training post. The Policy Manual says USCIS does not treat temporary, adjunct or limited duration fellowship positions as tenured or tenure-track, and research positions must be permanent. Time as a postdoc can, however, count toward the three years of research experience the beneficiary needs.
