USCIS Regulations
The controlling Code of Federal Regulations sections that define each category's evidence framework and adjudication standard.
-

Regulatory definition, 6-criterion evidence framework, and the 3-year experience and qualifying-employer requirements for the outstanding-researcher category.
-
8 CFR 204.5(k)
EB-2 — Advanced-degree professionals and aliens of exceptional ability

O-1 — Aliens of extraordinary ability or achievement
Regulatory definition, the 8-criterion extraordinary-ability evidence framework for O-1A, the advisory-opinion requirement, and the itinerary and qualifying-engagement rules.
AAO & Federal Precedent
Binding precedent decisions that shape how USCIS adjudicates extraordinary-ability and national-interest-waiver petitions.
-
Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010)
Established the two-step extraordinary-ability adjudication framework: (1) objective count of the regulatory criteria met, then (2) a final merits determination on whether the record as a whole shows sustained national or international acclaim. Applied to EB-1A and, by adoption, to O-1A.
-
Matter of Dhanasar, 26 I&N Dec. 884 (AAO 2016)
Controlling precedent for EB-2 National Interest Waiver. Replaced the NYSDOT framework with the three-prong test: substantial merit and national importance, well-positioned to advance the endeavor, and balance favoring waiver of the job offer and labor certification.
-
Matter of New York State Dept. of Transportation, 22 I&N Dec. 215 (AC 1998)
The pre-Dhanasar NIW framework. Superseded by Dhanasar in December 2016 but cited in older case law and AAO decisions for historical context.

Glossary
Terms you'll encounter in employment-based petitions and the AutoPetition workspace.
- Priority Date
- The date USCIS receives a properly filed I-140 (or, for PERM-required categories, the labor certification). Determines a beneficiary's place in the visa queue per the Visa Bulletin.
- I-140
- Immigrant Petition for Alien Workers. The primary petition form for employment-based green-card categories including EB-1A, EB-1B, EB-2 NIW, and EB-3.
- I-129
- Petition for a Nonimmigrant Worker. Used by employers and agents to petition for O-1A and other non-immigrant work classifications.
- I-485
- Application to Register Permanent Residence or Adjust Status. Filed inside the U.S. to move from a non-immigrant status to lawful permanent residence when a visa number is current.
- Final Merits Determination
- The second step of the Kazarian adjudication framework: after confirming an applicant has met the minimum regulatory criteria, the adjudicator assesses whether the evidence as a whole demonstrates the required level of acclaim or national importance.
- RFE
- Request for Evidence. A USCIS notice asking the petitioner to supply additional documentation. Typical response window is 87 days.
- NOID
- Notice of Intent to Deny. A stronger USCIS notice signaling the adjudicator is leaning toward denial and inviting rebuttal evidence before final action.
- Premium Processing
- A USCIS option (fee-based) that guarantees an adjudication action — approval, RFE, NOID, or denial — within a defined window (typically 15 business days for I-140 EB-1A and EB-2 NIW).
- Concurrent Filing
- Filing Form I-485 together with Form I-140 when the beneficiary is inside the U.S. and a visa number is immediately available per the Visa Bulletin.
- Advisory Opinion
- A written consultation required for most O-1A petitions from a peer group, labor organization, or recognized expert in the beneficiary's field.
- PERM
- The U.S. Department of Labor's Program Electronic Review Management process for obtaining a labor certification. EB-1A, EB-1B, and EB-2 NIW are exempt from PERM; most other EB-2 and EB-3 petitions require it.
- AAO
- USCIS Administrative Appeals Office. Hears appeals of certain USCIS decisions and issues precedent decisions such as Matter of Dhanasar.
- Endeavor
- In the EB-2 NIW context, the proposed work or field of activity the beneficiary intends to pursue. Dhanasar prong 1 requires the endeavor to have both substantial merit and national importance.
