I had RFE on AP for my spouse
The RFE is for marriage certificate. My lwayer told me, marriage certificate goes only with 485 form, not with AP, so for some people they asking this. I got my AP and mailed the marriage certificate for my spouse on 24th and AVM changed to "received response on 25th and process is resumed, and start singing same old song .......
Good Luck to you, be ready with another copy of marraige cetificate.
Any way it looks strange.... if they ask for another copy although they have the copy in their file. I don\'t know when would INS reduce this redundency....
