1. I got my EAD renewal (EB2 485 pending) and there is a notation :" siganiture waived". Why is that?
-Sometimes the applicant's signature is needed on the some kind of EAD. Yours does not need.
Any problems?
-No.
2. My AP renewal is still pending. I plan to go back to China next week.
2.1 By reading previous post, I understand that if the AP is approved before my departure date, I can still mail it to China and use it to come back. Correct?
-Yes.
