My Fiance was disappointed at all the preparation we did for the interview and she was not asked to show anything, non of the documents we prepared were asked to be shown not even the photos of us together, the only thing she had to show was the Cenomar and Birth Certificate. The Interviewer was very nice and made my wife feel at ease. My wife was there a total of 3 hours from the time she walked in the front door of the US Embassy, it was all very easy and organized.
