I got there about 10 minutes ahead of time for my interview. Highly recommend getting a place within walking distance of the embassy. It might cost a little extra but the peace of mind is worth it especially considering the morning rush hour traffic. Waited a while in the seating area. The first appointment was for document verification/biometrics. The actual interview was about another hour or so later. The focus of the interview was completely about my wife and whether she had enough financial resources to support me. The fact that I had a six figure job offer already pending the outcome of the interview did not matter to the interviewer and actually worked to my disadvantage. The officer reasoned that it looked like my wife was "moving because of me and not because she wanted to". Had to provide her college/school transcripts, US bank statements, a lease agreement with her parents and (probably most importantly) a letter of employment from a US employer ( please note that it was only an offer. She did not end up accepting it but the fact that she had a job lined up to support us played a very important part). Was approved after about 10 to 15 minutes of questioning
