1. just found out from USCIS my I485 case still has my old address on file, and i just submitted a online address change. What if they sent any notice/approval letter to my old adress and nobody's there to accept it? Since online status change isn't reliable these days.
2. My AP expires in Nov 2, 2011 and i'm planning a trip to china from Sept to Oct 18 2011 while my I 485 priority date has met and USCIS should make a desicion soon. My questin is, if my case was approved/denied while i was in China, can i still use AP to enter US?
thanks.
