Thanks. I did not notice any document on the officer's desk. I think everything she was working with was on her PC. She had mentioned that something had not come yet so I assume she was referring to the I-751. She asked for evidence of a continuing marriage; I had pictures, joint bank statements, insurance cards, mortgage statements, tax transcripts, marriage certificate and our kids' birth certificate (all of these were already uploaded with the N400 application). She asked to see the marriage certificate and only made a copy of the birth certificates.
