The first preference holds three classifications that share a queue and very little else. One is self-petitionable, one needs an academic or research employer, and one needs a corporate transfer history. Picking between them is mostly a question of which your record already fits.
- EB-1A: self-petition, three of ten criteria, very top of the field
- EB-1B: employer files, two of six criteria, internationally recognised as outstanding
- EB-1C: employer files, no criteria, one qualifying year abroad
- None requires a labour certification
- Only EB-1A requires no job offer at all
Side by side
| EB-1A | EB-1B | EB-1C | |
|---|---|---|---|
| Who files | The person, or anyone on their behalf | A U.S. employer | A U.S. employer |
| Job offer | Not required | Required, and it must be a qualifying position | Required, as a statement describing the duties |
| Criteria | At least three of ten, or one major award | At least two of six | None |
| Standard | "one of that small percentage who have risen to the very top of the field of endeavor" | "recognized internationally as outstanding in the academic field" | Meets the regulatory definitions of managerial or executive capacity |
| Experience requirement | None stated | At least three years teaching or research | One year abroad in the last three |
| Comparable evidence | Available | Available | Not applicable |
| Labour certification | Not required | Not required | Not required |
EB-1A: the self-petition route
The distinguishing feature is in the regulation's first line: "An alien, or any person on behalf of the alien, may file an I-140 visa petition". No employer, no job offer, no labour certification. What it asks in exchange is the highest standard of the three, and a record built across at least three of the ten criteria.
It suits people whose recognition is portable and documented: researchers with citation records, engineers with adoption evidence, founders with press and funding, practitioners with judging seats and memberships. Which criteria to build first is the starting point, and when your profile is ready to file covers judging readiness.
EB-1B: fewer criteria, more conditions
Two of six is a genuinely lighter evidentiary load, and one criterion is meaningfully easier than its EB-1A counterpart: EB-1B asks for "original scientific or scholarly research contributions to the academic field" with no requirement that they be of major significance.
The conditions are where it narrows. An employer must file. You need three years of teaching or research experience. And the position must be tenured, tenure-track, or permanent as the regulation defines permanent, which is where fixed-term postdoctoral appointments often fail. EB-1B outstanding professors and researchers works through all of it.
One inversion worth noting: EB-1B's awards criterion asks for "major prizes or awards", while EB-1A's asks for "lesser" ones. On that single criterion EB-1B is harder, even though the overall standard is lower.
EB-1C: not about acclaim at all
EB-1C asks a completely different kind of question. There is no acclaim to prove and no criteria to satisfy. Instead the petition documents a year of managerial or executive work abroad within the relevant three-year window, a qualifying relationship between the overseas and US entities, and a US employer that has been doing business for at least a year.
Because the regulation defines managerial and executive capacity element by element, this is a documentary and definitional exercise rather than an evidentiary one. EB-1C multinational executives and managers covers the definitions and the two limits that decide most cases.
How to choose
Start from what you already have rather than from which looks easiest.
- No employer willing to petition? EB-1A is the only EB-1 option, and the NIW is the other self-petition route
- A tenure-track or permanent research offer in hand? EB-1B is likely the lighter lift on evidence
- A year abroad with a related company in a managerial or executive role? EB-1C may fit with no acclaim evidence at all
- A strong portable record and no employer constraint? EB-1A keeps the most control in your hands
- More than one might fit? That is a conversation with your attorney, not a decision to make from a table
Two structural points apply whichever route you take. All three sit in the same first-preference queue, so priority dates and retrogression affect them alike. And EB-1A and EB-1B both run the same two-step review, so clearing criteria is only the first half of either case, as the final merits determination explains.
If you may end up filing more than one petition over time, priority date retention is worth reading early rather than late.

Which classification to pursue, and in what order, is a legal judgement that depends on facts an article cannot see.

Frequently asked questions
Which EB-1 classification can you file yourself?
Only EB-1A. The regulation allows the person or anyone on their behalf to file, and no job offer is required. EB-1B and EB-1C both require a United States employer to petition.
Is EB-1B easier than EB-1A?
It needs two of six criteria rather than three of ten, and asks for international recognition as outstanding rather than the very top of the field. But it requires an employer, three years of experience, and a qualifying permanent or tenure-track position.
Does EB-1C require proving acclaim?
No. EB-1C has no evidentiary criteria. It turns on a qualifying year abroad in a managerial or executive capacity, the corporate relationship between entities, and the US employer doing business for a year.
Do all three share a priority date?
Priority dates attach to approved petitions and can be retained across employment-based classifications under 8 CFR 204.5(e), which is worth understanding if you may file more than one.
Can you pursue more than one?
That is a legal and strategic question for your attorney, and it depends on your status, your employer, and your timing rather than on anything an article can assess.
