I am currently on non-profit H1B (in university) with expiration of Dec 2023. My current contract will expire at the end of October 2021. The International student office asked to leave US immediately after my current contract expires because they will revoke my H1B and I won’t have 60-days grace period. I am confused their statement that I won’t have 60-days grace period after h1b revoked. Does anybody know whether the office is correct or wrong? If I have 60-days grace period, what shall I do to active the grace period?
