I got to the Embassy at 6am and waited in line. (Dress warm!) Once in the building, I went through security and got in the elevator. Best tip I received was to go to the very back of the elevator, you'll be the first one out. Wait in line, pay your fees and get a number. You will get called up to a kiosk twice to show your documents. The final time I was called up was for my interview. Wonderful gentleman who was to the point, very sweet and then proceeded to give me a great Halloween gift! All in all, other than my wait time outside, I was there for two hours.
