Candidates on O1DMatch arrive with profiles, evidence summaries and O-1 readiness indicators — the record is organized before you ever see the person.
Timing: this year's H-1B cap closed on July 17, 2026 and the next registration window is approximately March 2027. The O-1 files year-round, and premium processing returns a decision in 15 calendar days. For infra roles the cost of an unfilled seat is measured in GPU-hours — the O-1's year-round, 15-day-decision timeline is a budget argument, not a legal one.
The fastest way to see whether this pool holds your next ML infrastructure engineer: paste the listing. A person replies with matches, or with an honest "no match yet."
