I need some insights on this situation as well. I'm currently waiting for the final approval of 485 (filed on 7/24, received EAD in Sept. and AP in Nov.). But I got a job opportunity in China that I really don't wanna let it slip by and will have to move back in April or something. I'll try to get hired in the US and simply work in China. Just wondered if that's okay for me to stay in China while waiting for 485 approval?
Many thanks to any comments on this.
