I have changed my status from F2->F1->H1. My H1 was just renewed, starting from 9/1/07. I'm leaving for China in two weeks. I have two questions:
1. When I exit U.S., my renewed H1 hasn't started yet. Shall I surrender the I-94 on the latest I-797, which start from 9/1?
2. What documents should I prepare for in order to apply for the H1 visa in China? Please note that I have changed status twice.
Thanks a lot for any help.
