My interview was easy. IO did not ask us much. I think the interview was just 5 minutes. She wanted to know my father, mother name, where did we first meet, how long we have been married and that's it. She did not ask for any supported documents during the interview. We thought it was done successfully but we missed one notarized document that she needed. I did not bring the original of that document either so she could not make a copy instead. The IO ask us to mail her that paper to approve my application. We sent that notarized paper right away after the interview. Hope we will heard from her soon
