Interview was today October 26th. I arrived at 645 and was the second person there. Eventually we lined up and they started letting people into security. There were 2 people in front of me and somehow I was actually first person into the building and to get a ticket.. Lucky me. Turns out I was sitting near David Gandy (male model for M&S) but I don't think anyone else recognised him haha.
I was called about 10 people in and went to my first interview. Guy was really nice. Asked for bunch of stuff including police, birth certificate, Ds160, passport and affidavit. Asked when I wanted to fly, I said next week and he signed it off and told me to go back and wait. Waited another 20-25 min and then called up a second time. Lovely lady who asked me a few basic questions such as "when and how did you meet" "What does your fiance do for a living" "Which college are they at" e.t.c - informed me my visa was approved and off I went a happy man. All in all I was in there for about an hour and 15 min.
