Hi,
Just received the EAD/AP card after filing I-485. I want to visit China and return with AP. My question is I I changed my status from B1 to F1, then to H1 before. Will there be any issue to re-enter US by using AP just because I changed the status before?
-No.
Another question is: When I leave US, do I need to turn in I-94 from the H1B approval notice?
-Yes. You will get the new I-94 when you return to US using AP.
Thank you so much.
