H1B失业，如果在GRACE PERIOD期间转B2，B2 PENDING 时找到工作，
1. 是不是可以马上转回H1B？
-Yes, but the problem is that if the H-1 is approved first, the B-2 is approved later, then you need to go outside US to get the H-1 visa to come back.
还是要WITHDRAW B2 后才能转回H1B？
-No. Unless you file H-1 transfer during the grace period, you cannot withdraw the B-2 because there is status gap if you do it.
2. 如果B2 PENDING 期间找到工作，收到H1B petition 的 RECEIPT 就可以上班吗？
-Yes. See the above answer to question 1.
还是要得到APPROVED才能上班？
3. 如果B2 APPROVED 后找到工作，如果B2 PENDING 期间找到工作，收到H1B petition 的 RECEIPT 就可以上班吗？
-No.
还是要得到APPROVED才能上班？
-Yes.
谢谢8老师。
