回复：回复：回复：非常紧急求助：F-1签证，没有更新I20，导致身份失效，有什么办法吗（学校OISS的错误导致）

还有一个问题，我下学期的课可以正常上吗
-Yes.

还有，我的GA合同会不会受影响，我是暑期学期入学的，课都上完了
-Technically you can not work because you are not in F-1 status, but practically it might be OK for you to continue to work on-campus because after you get the F-1 reinstatement, your F-1 status has no gap and thus, USCIS might not tell your illegal work.  Ask your school to issue the new I-20 with the effective date on the date your old I-20 expired, thus your F-1 status will have no gap after you get the F-1 reinstatement. Also, if you visit China and come back using a visa (F-1, H-1, etc.) in the future before you apply for green card (file I-485), your illegal work record will be removed automatically.
