answer for klpd4dc, I went overseas twice and neither time I registered with USCIS, which I think I should have. Currently I have an RFE on my application for AP. The IO who generated the RFE is expecting to see the FIN# on my latest I-94. My lawyer has responded to the RFE and I have not seen any progress since then, other than a change in LUD with a change in message that says,"We received your response to our RFE...."
I just received my EAD card today. So at this point, me and my wife have three applications pending:485s for both of us and that AP for me.
