回复：F1身份出了问题，紧急求助！！！

You will only have a problem IF your I-20 HAS ALREADY EXPIRED before your graduation, and you're now out-of-status. Next step will be to reinstate or to leave US.
But if it's still not expired, ISO can extend it, fix it easily, and you still have OPT for this time if not yet graduated.

从法律上讲，如果一个学生最后一个学期结束，必须在多长时间内离境？for those who graduate, 60 days, for you, no grace period if not graduated.

如果我能在最后几天内找一个新的I20，还能挽救我的F1身份吗？ If current I-20 already expired, no, because you have no F-1 status now. You need to reinstate.
