Overall it turned out good because we got APPROVED! The only thing is going over there early in the morning. (it was raining and we caught a cab from across the street lol!). Lots of people trying to get in, if you don't stand your ground they will go around (and in front) of you... Have your papers ready, you will have to show your appointment confirmation to get in. After you get in you will have to sign-in and wait for your turn. Interview was pretty quick (probably five minutes or so), pay a few fees and get out.
