So my wife had her interview today August 4th, 2020 in the midst of this pandemic. We actually got the interview expedited. My wife said she arrive like 2 hours early and since there was no one they let her in and interviewed her. She told me they didn't really ask for any documents. Only documents they asked were Birth and Matriage certificate and my I864 and w2s. Another thing they asked for was my sons passport, as he was the reason for our expedite. She said the interview went so quick. The officer didn't even as questions pertaining our relationship. Overall she said it was a pleasant experience. Maybe because she was the only one being interviewed.
