EB-1B is the US green card for outstanding professors and researchers. If you have at least three years of teaching or research experience and a permanent job offer from a US university, university-affiliated research organisation, or private research employer with documented achievements, this is often the cleanest path to a green card.
The bar is real but narrower than EB-1A. You need 2 of 6 criteria, major prizes, association memberships requiring outstanding achievement, published material about your work, judging the work of others, original scientific or scholarly contributions of major significance, or authorship of scholarly books or articles. There's no 'sustained acclaim' wrapper; the 'final merits' analysis is lighter than EB-1A.
Petitions are filed by the US employer (not self-petitioned). The role must be tenure-track, tenured, or a comparable permanent research position. For industry research roles, the employer needs to have a department or division engaged in research and document that. Premium processing is available; processing runs similar to EB-1A.
Is this visa for you?
A strong fit if you…
- You're a tenure-track or tenured professor with a US university offer in hand, or about to receive one.
- You're a research scientist at a national lab, pharma, biotech, or a corporate research division (Google DeepMind, Microsoft Research, Meta FAIR, etc.) with a permanent role.
- You have a PhD plus 3+ years of post-doctoral research or teaching experience and a publication record with real citation impact.
- You're a strong EB-1A candidate but have a clean university or research employer ready to file, EB-1B's 2-of-6 framework with light final merits is structurally easier.
Look elsewhere if you…
- You don't have a permanent research or teaching offer. EB-1B is employer-sponsored, without the offer there is no petition.
- Your research role is short-term, post-doc, or project-based without a clear permanent designation. Visiting scholars and most post-docs don't qualify.
- You're an industry engineer doing applied work that isn't framed as research. EB-1B specifically wants a research role, not product engineering. EB-1A or EB-2 NIW fits better.
Key requirements
- Meet 2 of 6 outstanding researcher criteria
- 3+ years research/teaching experience
- Permanent job offer from US university or research institution
Eligibility, in plain English
3+ years of research or teaching experience
USCIS counts academic research, industry research, and university teaching toward the three-year minimum. Time spent doing your PhD usually counts if you can show you were paid as a researcher (RA appointments). Industry research counts if the role was research-classified internally.
Permanent research or teaching offer
Tenure-track or tenured at a university, or a comparable permanent research position at a research institution. For private employers, the petition must show the employer is a private organisation that employs at least 3 full-time researchers and has documented accomplishments in the relevant field. Corporate research divisions usually qualify; product engineering teams usually don't.
Two of six criteria
Major prizes, association memberships requiring outstanding achievement, published material about your work, judging others' work, original contributions of major significance, or authorship of scholarly articles or books. Most academic researchers meet authorship and judging easily; original contributions is where the case lives or dies.
Major prizes for outstanding achievement
Nationally or internationally recognised research awards. Named fellowships (Sloan, Packard, NSF CAREER), best paper awards at major conferences, society-level recognitions. Submit the selection process and pool size to show selectivity.
Original scholarly contributions of major significance
Citation counts (h-index, top-cited papers), products or treatments derived from your work, regulatory adoption, follow-on research building on your work, letters from independent experts tying your contribution to wider-field change. This is the hardest criterion to meet cleanly, the bar is 'major significance', not just 'cited'.
Scholarly articles in major venues
Peer-reviewed publications in well-regarded journals or conference proceedings. Tier matters, Nature, Science, top medical journals, NeurIPS, ICML, top venues in your field. Submit citation counts and journal impact factors. First-author or senior-author publications carry more weight.
Judging the work of others
Peer review for journals, conference program committee membership, grant review (NSF, NIH, ERC). Document invitation emails plus a record of completed reviews. For academic researchers this is usually the easiest criterion to evidence.
How the application actually goes
- 01
Lock in the permanent offer
The offer letter has to designate the role as permanent (tenure-track, tenured, or comparable permanent research). For industry research employers, the offer letter and supporting documentation must establish the research department and the role's research nature.
Varies
- 02
Audit research and teaching experience
Document 3+ years of qualifying experience. Pull employment letters, appointment letters, RA/post-doc records. Time outside the US counts if documented.
1-2 weeks
- 03
Build the evidence package
Letters from 5-8 independent experts (not co-authors or collaborators), citation reports, publication list, judging records, awards documentation, organisational letters establishing employer/role suitability.
6-10 weeks
- 04
Employer files I-140
Petition filed by employer on Form I-140 with substantial supporting documentation. Premium processing ($2,805) gives a 45-day decision. Without premium, processing runs 6-15 months.
45 days (premium) or 6-15 months
- 05
Adjust status or consular process
If your priority date is current and you're in the US, file I-485. If abroad, consular processing. India- and China-born applicants face priority date backlogs measured in years.
8-14 months (I-485) or 4-10 months (consular)

Common pitfalls
- Filing for a post-doc or visiting position. EB-1B requires a permanent offer. Post-docs are by definition temporary even when multi-year, and visiting positions don't qualify.
- Industry research petitions without proper employer documentation. The employer has to establish that it's a private research organisation with at least 3 full-time researchers and documented research achievements. Casual claims don't survive RFE.
- Letters of recommendation from co-authors or current/former PhD advisors. Independent letters carry vastly more weight. Replace at least half your letter writers with people you haven't collaborated with directly.
- Treating EB-1B as easier than it is. The 'original contributions of major significance' criterion is the same evidentiary bar as EB-1A's version. Don't write thin contribution arguments and expect them to pass because there are only six criteria.
- Filing during a tenure-track conversion gap. If your appointment is technically still post-doc until tenure review, USCIS may reject as non-permanent. Wait for the tenure-track letter before filing.
- India- or China-born applicants underestimating the priority date wait. Even with a clean approval, the visa number may not be current for years.

Frequently asked
Do I need tenure-track for EB-1B?
You need a permanent offer. Tenure-track and tenured both qualify cleanly. For industry, the role must be a permanent research position at an employer with a documented research function. Indefinite-but-at-will employment counts as permanent for EB-1B purposes.
Can I file EB-1B as a post-doc?
Generally no, because post-doc appointments are by definition temporary. If you're being converted to a permanent research position or tenure-track role, file once the new appointment is confirmed.
How is EB-1B different from EB-1A?
EB-1B has 2-of-6 criteria (vs 3-of-10 for EB-1A) and a lighter final-merits read. The trade-off: EB-1B requires a permanent research employer offer, while EB-1A is self-petitioned. For academic researchers with offers, EB-1B is usually the easier path.
Does industry research count?
Yes, if the employer qualifies. Microsoft Research, Google Research/DeepMind, Meta FAIR, IBM Research, pharma R&D divisions, and similar all routinely sponsor EB-1B. Product engineering teams generally don't qualify, even at the same companies.
What if I'm a research scientist at a startup?
Possible but harder. The employer needs to document at least 3 full-time researchers and accomplishments in the research field. Most early-stage startups don't clear this. EB-1A or EB-2 NIW are usually better paths from a startup research seat.
How long does premium processing take?
45 calendar days for an I-140 decision (approval, denial, or RFE). That's longer than I-129 premium (15 business days) because I-140 review is more substantive.
Can I switch employers after I-140 approval?
EB-1B I-140s are generally tied to the original employer. If you change jobs before I-485 approval, you may need a new I-140 from the new employer. Once you've been on an approved I-485 for 180+ days, AC21 portability lets you change to a same-or-similar role at a different employer without re-filing I-140.
