My GC was approved on 3/17/08, my wife got RFE on 3/18/08 and RFE was received on 4/3/08. Today her GC approved, but she will go back to China for a 2 week visit on 4/12/08. Guess that she has to take AP with her, will that be a problem for her to come back with AP after her GC approved but haven't got the real card? Thanks.
