8老師，請進，這個問題接著問：

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

1. 如果丟了工作, 是否必須立刻離境?

-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.

 如果丟工作後，雇主通知了USCIS，USCIS是否會取消雇員現在持有的有效H1B？還是USCIS不對丟了工作的H1B持有人采取任何行動？謝謝回答。

2. 如果幸運3月排期到, 遞485申請後丟了工作,多長時間找到工作不影響拿GC?

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

或者等找到下家再遞485?

-Up to you.
