My wife's interview was at 7:30 am we arrived at 7 and it was already packed. The security guy comes and orders two lines one for 7:30 am and another for the 8am interviews. Once inside they collected our documents and asked fee basic questions like when she got married and who is calling her. As for the interview itself, it was quick and painless a friendly CO greeted her and asked few basic questions like; What is your husband doing in U.S, who he stays with, what his parents do for a living. All while nodding and typing away on a computer. She had soo many photos and call logs and travel itenararies as proof, none of which they asked to see. It almost seemed like the decision was made prior to the interview even starting. After interview the CO told her she was approved and her visa will be ready in a week. But we got an email the very next day at evening saying the visa was ready for pickup. So we received the visa just 2 days after interview. Overall good experience. Only complaint was the overall interview took about 3 hours, there is a lot of waiting involved.
