I am on H1, with wife and kids on H4. Nov 2001, filed 485 for myself and kids. Didn't file for wife as we were separating. Now, we are reuniting; she's overseas with kids; her VISA (H4) is valid till 2004. Kids have AP but have NOT utilized yet. Questions: a) can I file her 485 now? b) If yes, how soon can kids use AP after her 485's filing (I am assuming that usage of AP will invalidate H4)? Appreciate any advise/caveats etc.
