EB-1A does not require any specific degree. The regulation at 8 C.F.R. § 204.5(h)(3) lists ten evidentiary criteria — awards, membership, published material, judging, original contributions, scholarly authorship, artistic exhibitions, leading or critical role, high salary, and commercial success in the performing arts — none of which references a PhD. A petitioner satisfies the regulation by demonstrating receipt of a major internationally-recognized award, or alternatively by satisfying at least three of the ten criteria, after which USCIS conducts the Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010), final-merits analysis.
The comparable-evidence provision at 8 C.F.R. § 204.5(h)(4) is central to many non-academic EB-1A cases. Where one of the ten criteria does not readily apply to the petitioner's field of endeavor, the regulation permits the submission of comparable evidence "to establish the beneficiary's eligibility." The provision is field-specific: a petitioner whose field does not have, for example, scholarly journal publications in the conventional sense can submit equivalent forms of recognition under the comparable-evidence framework.
The USCIS Policy Manual addresses comparable evidence at Volume 6, Part F, Chapter 2, and emphasizes that the petitioner has to first show that the standard criterion does not readily apply before the comparable-evidence provision is invoked.
In current adjudications, RFEs on non-PhD records frequently challenge the original-contributions criterion at 8 C.F.R. § 204.5(h)(3)(v) and the scholarly-authorship criterion at (vi). Officers sometimes assume — incorrectly under the regulation — that scholarly authorship requires peer-reviewed journal publication and that original contributions have to be documented through citation counts. Both of those assumptions are rebuttable and have been rebutted in past cases.
