Sorry, just thought another question.
My wife is the same status as me (H1B with A, used AP last year, but did not use EAD so far). We are not sure whether she will be able to find a job in the city B (where B is) in the near future. I believe she can stay legally even she has no job in City B for a while (as she used AP, so technically she is AOS now). To be 100% safe, should I change her to H4 (using Form I-539)?
your answer: -Not necessary. If her I-485 has problem, just go to China to get the H4 visa to come back.
If her I-485 has problem (do you mean accidentally denied in error? BTW I am the primary of our green card application), would she be out of status since she used AP last Oct.? If so, without a H4 status, will she be barred for some years from entering US? I know this is small small chance event, but I just wanted to understand the full picture.
3X again!
