Underrated and highly winnable — peer review, program committees, and grant panels map directly onto this criterion, and researchers, engineers, and physicians accumulate this work without realizing it counts.
What USCIS actually looks for
Evidence that you have participated, individually or on a panel, as a judge of the work of others in the same or an allied field. The core signal USCIS wants: you were selected to evaluate the work of your peers because of your own standing. A meaningful judging role — deciding what gets published in a strong journal, what gets accepted at a competitive conference, or which projects get funded — carries far more weight than a token one.
Common evidence that works
Invitation/assignment emails from journal editors or conference chairs
Confirmation from the journal's editorial system (e.g., Publons/Web of Science reviewer record, editor manager screenshots)
Program-committee or grant-panel appointment letters
The prestige of the venue — impact factor, acceptance rate, the funder's national standing
Volume — a documented record of multiple reviews reads as sustained, not one-off
Common mistakes — why petitions fail this criterion
No documentation. "I reviewed papers" without invitations or a reviewer record proves nothing.
Reviewing for obscure or predatory venues — the prestige of what you judged matters.
Internal-only judging (grading your own students, reviewing your employer's internal work) — USCIS wants judging of the field's work.
Failing to redact confidential manuscripts when submitting review samples.
How Dr.EB1A builds this criterion
Dr.EB1A pulls your reviewer history from the records you upload (Publons/ORCID exports, editor emails, committee letters), tallies your review volume, attaches venue-prestige data to each, and drafts the argument that you were selected as a peer-recognized expert. It flags any confidential material that must be redacted before filing.
Short example
An engineer thought his peer-review work was "just volunteering." Dr.EB1A assembled his Publons record — 23 reviews across four IEEE journals — added each journal's impact factor, and drafted a judging exhibit that became his cleanest, least-disputable criterion.
