Hi,
I went today. I took the subway green line to Govt. Center. If you come out of the 'T' station you can see people standing in a line to enter JFK building. I reached there around 7:15 a.m. and joined the queue. Already there were around 200 people ahead of me. After the usual security check, got in the building around 7:30 and stood in the queue for another 45 minutes to get the token. Then went for signature and finger print - which is actually the impression of the index finger and it didn't take any time at all. Waited for another 30 minutes in a hall and got the stamping in the passport. It was pretty fast.
To the officer at the counter I gave,
1. the ADIT pictures taken at Sears.
2. the courtesy copy of the approval letter (nobody questioned it - I was worried that they might ask for the original one).
3. I 94
4. H1B approval ( to show my vaild status. I don't have an EAD. But the officer didn't care about this)
The only question he had for me was if I have Advanced Parole and stamped my passport.
Good luck to you.
