# USCIS O-1, EB-1 and NIW petition letter pack > Draft extraordinary-ability and national-interest USCIS petition packs with criterion-mapped cover letters, evidence indexes, advisory opinion requests, recommendation letters, and RFE response structure. Tags: Immigration, United States, USCIS, O-1, EB-1A, EB-1B, EB-2 NIW, Legal ## Example Prompts - Draft an EB-1A cover letter and evidence index for a machine-learning researcher - Create an O-1A petition pack with advisory opinion request and referee letter templates - Compare EB-1A, EB-1B, and NIW options for a physician-scientist - Build an NIW Dhanasar petition letter for a climate-tech founder - Prepare an RFE response outline for weak EB-1A original contribution evidence URL: https://rakenne.app/skills/uscis-o1-eb1-petition-letter-pack/index.md Try this skill: https://rakenne.app/a/?skill=uscis-o1-eb1-petition-letter-pack ## Overview Draft extraordinary-ability and national-interest USCIS petition packs with criterion-mapped cover letters, evidence indexes, advisory opinion requests, recommendation letters, and RFE response structure. Use it to compare O-1A/O-1B, EB-1A, EB-1B, and EB-2 NIW pathways, then build the petition around a clean evidence spine: legal criterion or Dhanasar prong, exhibit number, page range, argument, and risk note. ## What It Covers - O-1A and O-1B petition cover letters with advisory opinion request templates. - EB-1A cover letters using the Kazarian two-step analysis. - EB-1B outstanding professor or researcher petitions with employer and permanent-offer checks. - EB-2 NIW cover letters using Matter of Dhanasar's three-prong framework. - Expert recommendation letter templates and RFE response wrappers. ## Example Conversation > **You:** I’m preparing an EB-1A petition for a machine-learning researcher. She has 24 publications, 1,800 citations, program committee reviewing, a best paper award, and letters from two independent professors. Can you draft the cover letter and evidence index? > > **Agent:** I’ll structure this as an EB-1A I-140 package. First I’ll map the evidence to the 10 criteria, then draft the Kazarian Step 1 threshold section and the Step 2 final merits analysis. I’ll also flag any weak or missing evidence for counsel review. > > **You:** Please include a referee letter template for the original contributions criterion. > > **Agent:** I’ll add an independent-expert letter focused on field-level significance, citations, adoption, and how the work compares with ordinary publication output in the field. > ## Sample Output Excerpt Excerpt from an EB-1A evidence index and cover-letter section generated by the skill: --- ### Criterion: Original scientific contributions of major significance in the field **Evidence cited:** Exhibits 8–14, including citation report, independent expert letters, open-source adoption metrics, patent filings, and deployment evidence from two external research labs. The record demonstrates that Dr. Rivera’s work on privacy-preserving model evaluation is not merely original, but has achieved field-level significance. Her 2022 paper has been cited 640 times, incorporated into two benchmark suites, and independently adopted by research teams at [Institution A] and [Institution B]. As Professor Chen explains in Exhibit 11, the method changed how labs validate sensitive medical imaging models without centralizing protected data. | Exhibit | Page range | Criterion | Evidence description | Argument use | | ------- | ----------: | ---------------------- | ------------------------------------------- | --------------------------------------------------- | | Ex. 8 | pp. 120–138 | Original contributions | Citation report and benchmark adoption data | Shows independent uptake and field-level use | | Ex. 11 | pp. 167–172 | Original contributions | Independent expert letter | Explains technical significance and peer comparison | ## References and Templates This skill does not ship executable validation tools. It includes structured drafting resources instead: - **Regulatory criteria table** for O-1A, O-1B, EB-1A, EB-1B, and NIW/Dhanasar mapping. - **Evidence index template** with exhibit numbers, page ranges, criterion mapping, strength notes, and follow-up gaps. - **Cover letter templates** for O-1, EB-1A, EB-1B, and EB-2 NIW petitions. - **Advisory opinion request templates** for O-1 peer group, labor union, management organization, and individual expert consultations. - **Recommendation letter templates** for independent experts, collaborators, organization leaders, compensation evidence, and NIW national-importance support. ## Getting Started Bring the candidate’s CV, target classification if known, publication and citation records, awards, memberships, judging activity, press, salary evidence, employment or agent details, proposed endeavor for NIW, referee list, and any USCIS RFE text. The skill will help select the path, organize exhibits, draft the petition letter, and mark weak points for attorney review before filing. --- Back to [Skill Library](https://rakenne.app/skills/index.md)
