No Title
They have 2 lines, One for the people with appointments, you will be allowed to go inside immediatly(not big line).
The other one is for the people without appointment. This line actually starts from outside of INS building Broad Street(Number I don\'t remember)its better if you reach morning around 6AM, you can finish by 11 AM.
I went 8.30AM and came out at 1 pm
Good luck
