You only need to get there at least 20 mins before your interview the guard will send you away if you are there earlier. A lady comes out and checks you in and gives you a number. you go through security and instructed to go down the stairs and take the elevator up to the 19th floor. once you come out there are three sections. one for non immigrant and the middle for immigrant,..not sure what the last one was. You go sit in the middle section and wait for your number to be called.
the first window is when she asks for your passport original birth certificate and marriage certificate and police reports, she didn't ask for any photocopies, then she takes your fingerprints and gives you the domestic abuse pamphlet and tells you to sit back down and your number will be called again for the interview.
I waited for another hour and a half before i was called again. She was a very nice and pleasant CO - asked me
1) how did you meet your husband?
2) how long have you been married?
3) what does he do?
4) how often do you see him?
5) you will be living with him at (repeated address in US)?
6) have you ever been to the US? whats the longest you stayed?
7) Ever been denied a visa?
8) Ever been arrested?
And that was it. Interview was no more than 5 mins.,it just seems longer!
