The interview was pretty straight forward.
We (my fiance and I) got to the embassy around 7:30 for an 8:00 appointment. There was only about 6 people in line ahead of us at that point. It seemed that around 7:45ish (we both forgot our watches) they started letting people in. The lady at the front just needed our letter and our passports and we were on our way. I was shocked by the number of people who got turned away because of phones and other electronic stuff. Went through security and then headed to reception. The lady put a label on the letter that read 8:10 so it took about 25 minutes to get through security. We got to the waiting room and I-901 and I-902 numbers were called. Then there was about 30 minutes where it was all the 'N' numbers being called. Finally the 'I' numbers started to get called again and my fiancee was called. Handed in his paperwork and was told to sit back down. The only complaint he had was that the lady collecting his papers had a thick Asian accent and while pleasant was really hard to understand. About 10 minutes later he was called to the back desk(I went up with him this time) and there was a really friendly Southern American lady. She made a joke about some of the pictures we sent in with the fiance petition and then told my fiance he was approved. He took the oath and signed the form. We were paid up with the courier and out of there by about 9:30.
