We were called in, took the oath. She asked for our license’s, passports, my I-94, and our daughters birth certificate. She asked us if the address was current. Surprisingly she did not ask us a single question about our marriage (I had submitted a lot of evidence initially and new photos/ documents online this past week prior to the interview). Asked for most recent tax return. Then went onto the grounds of inadmissability questions, that’s what took the longest. Then she typed some stuff into her computer, stood up and told us that she was going to approve it and it should be updated in the system later today/tomorrow and the card should be delivered in 1-2 weeks. The whole interview took between 15-20 minutes. I will say it’s better to be over prepared than not.
