回複：Xiaobaitu and other experts: I-485 with O-1 and address chang

doesn't matter, as O-1 is similar to H-1, you can renew it while I-485 is pending.

Address change could be a problem. But if you call USCIS and file AR11, it should be ok (If you have several I-485 petitions pending, for each case number, you need to tell them the address change).
