[cal_aos_waiting]

Just last week the USCIS case status online said that my wife's case has been approved. Now, as of this afternoon, the message changed to "received". Not sure whats going on!!!!!!!!

Receipt Number: WAC0409******

Application Type: I765, APPLICATION FOR EMPLOYMENT AUTHORIZATION

Current Status:

On June 27, 2004, your I765 APPLICATION FOR EMPLOYMENT AUTHORIZATION was received here for processing. It is taking between 120 and 120 days for us to process this kind of case. We will mail you a decision as soon as processing is complete.

This is Uscis for you.
My I140 was approved and EAD issued ( May and June respective) ( 2nd EAD Issued in APR ..1st Ead Expring on 24th June) but MY I140 still shows that the RFE was Recd and they are Processing.
So I guess if your wife recieves her EAD card in the mail it shouldnt be aproblem.
