回复：8老师，请进，这个问题接着问：

1. 如果丢了工作, 是否必须立刻离境?

-Not necessary. If your H1 I-94 does not expire yet, you are legal to stay in US. So, just fine a job as soon as possible and do the H1 transfer. If your H1 transfer approval has no I-94 due to the status gap, just go outside US to get the H1 visa to come back.

 如果丢工作后，雇主通知了USCIS，USCIS是否会取消雇员现在持有的有效H1B？还是USCIS不对丢了工作的H1B持有人采取任何行动？谢谢回答。

-It does not make difference and your H1 transfer still can be approved, but the approval notice will have no I-94 and thus you just get the H1 vis outside US to activate your H1 status.
