My husband went for his interview this morning. So I will give you a brief account of his experience.
He arrived a little before his interview time of 9:30 AM. He went to through security as everyone has described in other reviews. He then went to the first desk and checked in. They sent him up to the interview area. The first person he encountered asked for his paperwork, passport etc. Then he was told to sit down until he was called to the next window. He waited about 10 minutes and was called up. He was fingerprinted and given the oath to tell the truth. He was asked a couple of minor questions about our relationship and when had he last seen is son who just turned 2 years old. Then the officer smiled and said "you are approved and should receive your passport and visa in 7 to 10 days." My husband was dumb struck. My mother and I loaded him up with a ton of back-up paperwork to take with him in case they requested something. I think he was mad that they didn't ask for any of it lol. We are now in AP and relieved that this almost over and he will be here soon.
