8老师，请进，这个问题接着问：

EB2, NIW I-140已批, PD 4-27-2010, 现在是H1B,

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。

2. 如果幸运3月排期到, 递485申请后丢了工作,多长时间找到工作不影响拿GC?

-As long as USCIS does not send your RFE for your employment status, your I-485 is safe.

或者等找到下家再递485?

-Up to you.
