How I moved from STEM OPT to O-1.

The criteria that were realistic

Only three of the eight were worth pursuing at first, and a fourth appeared as a side effect.

• Authorship of scholarly articles - already partially satisfied
• Judging the work of others - achieved through conference peer review
• Original contributions of major significance - built through expert letters tied to production adoption
• Critical capacity - documented via a team-lead role on a shipped model

Turning work into evidence, month by month

• Months 1-3: volunteered as a reviewer for two workshops, kept the invitation emails
• Months 2-6: wrote release notes and adoption metrics for the open-source project
• Months 4-8: gave three talks, requested confirmation letters from each organizer
• Months 6-10: collected six expert letters, half from people with no prior working relationship
• Month 10: salary benchmarked against BLS and Levels data for the same metro

Independent letters carry the weight

Letters from co-authors demonstrate collaboration, not recognition. The letters that mattered came from researchers who had used the work without ever meeting the author, and who could describe the specific impact on their own results.

Filing mechanics

An agent petitioner was used so consulting clients could be added later without a new petition. The itinerary and deal memos were prepared before filing, which is exactly the documentation an RFE would have requested.
