What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of henryknows.info controls every word below.
Ask HenryKnows
Send one question about F-1 or J-1 student immigration, SEVIS, OPT, CPT, transfers, status, travel, employment or related rules. Returns a cited answer in plain text: the answer, then the numbered sources (regulation, Federal Register notice, or agency guidance). Answers take 10 to 40 seconds. Add the word STUDENT at the start for plain language aimed at a student.

- Can an F-1 student work on campus during the 60-day grace period?
