Wife of citizen: 485 filed can wife stay in the US

[Tukaram21]

My wife filed for I-130 in May 2009 while I was a GC holder. I became a naturalized citizen in August. We have then filed 130/485/EAD/AP. My wife is currently in the US but her I-94 (through B-2) expires in Sept. Can she continue to stay in the US if

a) I-130 / EAD / AP gets approved
b) We have not yet heard back from that.

THanks a million
