The three categories, and who each is for
EB-1A is for extraordinary ability. It is self-petitioned — no employer and no job offer are required — which is why it is the route most independent researchers look at first. The evidence standard is the highest of the three.
EB-1B is for outstanding professors and researchers. It requires a qualifying permanent job offer from a US employer and at least three years of experience in teaching or research. Because an employer sponsors it, the evidentiary bar sits lower than EB-1A, but you cannot file it alone.
EB-1C is for multinational executives and managers transferring within a company. It is a business track. Publications are not part of its evidence at all, and a researcher without management responsibility will not qualify.
Only EB-1A can be self-petitioned. EB-1B needs an employer; EB-1C is not a research route.
How the evidence tests differ
EB-1A asks you to meet at least three of ten criteria set out at 8 CFR 204.5(h)(3), unless you have a one-time major achievement such as a Nobel Prize. Several of those ten are publication-related: authorship of scholarly articles, original contributions of major significance, judging the work of others, and published material about you.
EB-1B asks for at least two of six criteria at 8 CFR 204.5(i)(3)(i). The list is shorter and framed around academic recognition, so a strong publication and citation record can carry a larger share of the case.
Meeting the count is not the end of either analysis. Under Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010), the criteria are step one; step two is a final merits determination that weighs the evidence as a whole. A petition can satisfy three criteria on paper and still be refused at step two.
What this means for how you publish
If EB-1A is the realistic route, the record has to do more than exist — it has to demonstrate influence. That pushes toward fewer, better-placed papers in journals your field actually reads, and toward the kind of work that accumulates independent citations.
If EB-1B is available because a US institution is hiring you, the calculus shifts. The job offer carries weight the publication record would otherwise have to carry alone, and consistent output in recognised venues matters more than chasing a single high-profile placement.
Either way the work has to be real. A record assembled quickly in venues nobody in the field cites is visible as such, and it is the kind of thing that draws scrutiny rather than deflecting it.
