Judging Evidence
Official Definition
Evidence of the alien's participation on a panel, or individually, as a judge of the work of others in the same or in an allied field of specialization to that for which classification is sought;
What Adjudicators Look For
Under 8 CFR 214.2(o)(3)(iii)(B)(4), the beneficiary must have actually participated in evaluating other people’s work—not merely been invited, and not routine grading of one’s own students or internal peer feedback on team deliverables. The activity should sit in the same or an allied field as the O-1A classification.
Strong examples include peer review for scholarly journals (with evidence such as editor confirmation or reviewer history), study section or grant-review service for major funding bodies, program committee or competition judging for respected conferences or prizes, and external Ph.D. dissertation examination where you assessed another scholar’s thesis. USCIS expects documentation of performance (completed reviews, panel rosters with your service dates, thank-you letters from editors that confirm substantive review), not a bare invitation email.
Evidence Strength
Strong Evidence
Completed peer review for indexed journals, with editor confirmation or official reviewer records (without breaching confidentiality rules)
Grant or fellowship review panels for national or international agencies or foundations with documented participation
Conference program committees, best-paper committees, or hackathon/technical competition juries with published rosters
External thesis examination or dissertation defense roles in your discipline, documented by the institution
Editorial board service only when it entails substantive adjudication of others’ submissions (document the gatekeeping function)
Weak Evidence
Teaching assistant grading of problem sets or exams for a professor’s course
Routine internal code review or design critique within your employer, absent a field-wide recognized program
Local science-fair judging without evidence the role required expert evaluation comparable to your specialty
Invitations or nominations to judge that show no evidence you completed the evaluation
Stack Overflow, forum moderation, or informal mentoring framed as “judging” without structured selection of others’ work product
Common RFE Triggers
Common RFE Triggers
Invitation-only packets with no proof reviews, scores, or decisions were completed.
Conflating student evaluation or HR interview duties with judging the work of others in the field.
Activities outside the claimed field or so informal that they lack industry recognition.
Confidentiality over-explained: you redact content but still need credible third-party confirmation from editors, chairs, or official letters on letterhead.
Self-serving colleague letters without corroborating records from the journal, conference, or agency.
Tips for Strengthening Your Evidence
Pro Tips
Request a standard verification letter from the editor, program chair, or agency stating your role, approximate number of reviews or years of service, and field of the venue.
Keep non-confidential artifacts: thank-you emails, certificates of appreciation, public PC member lists, or official schedules showing your assignment.
Organize a table of judging activities with entity, dates, type of work evaluated, and exhibit references.
Prefer recognized venues in your discipline; if the forum is niche, add context on its selectivity and audience.
If you are early-career, combine multiple instances of service to show a pattern, not a one-off.
Relevant Document Types
Judging Evidence should hold confirmations, rosters, certificates, and redacted review acknowledgments. Recommendation Letter or Expert Opinion Letter from editors or chairs can corroborate participation. Publication may apply when official proceedings list you as a program committee member. Use Other for official panel appointment PDFs or agency letters.
