There is no much to say really.
My husband and I followed all instructions and the entire process was flawless until the day of the interview. The interview time did not take more than 30 minutes and I got out before my interview scheduled time because I had arrived few minutes earlier. The agent who I spoke to made it seem as if I am not being interviewed which was really good and made me comfortable. He asked few questions which I immediately answered while he was finishing up few things on my documentations.
I did not carry anything with me except what I was told to take to the interview. No phone, no jewelry. Entered simple and everything was simple.
