H1B, H4 Visa

OFC:
OFC was scheduled at 1:00 PM december 7th, but reached there before 11:00 AM.
There was a long queue outside and they allowed me into the queue only before 15 minutes of appointment (they didn't allow mobile and handbag inside, so i kept the belongings outside private locker which they charged 200 rupees only for 10 minutes).

Went to the counter exactly scheduled time and done giving the finger prints in just 2 minutes and came outside (at the time of giving finger prints he has asked me what is my purpose of travel to US)

H1B Interview:

appointment time is 9:AM on December 8th, but reached around 7:45 AM. Again there was long queue outside. They allowed me into the queue at 8:AM, after passing several queues i reached finger prints checking counter at 9:AM. I was asked to be wait for some time as they were checking my passport and verifying my details and finger prints (all the people were just moved to the next counter for visa interviews, but they didn't send me for verifying the details again. I got bit tensed. In several minutes they came back and called me for checking my finger prints again. This time they were satisfied and i moved to the much awaited VO counter.
