get there at 6:40am, the door opened at 7:05am, get in at 7:10am
When I got there at 6:40am, there were about 30 people waiting outside. It was Thursday, they only work for half day.
Generally, the people (guards, officers) there are very nice. But you definitely want to get a male officer to take care of your case. That\'s just my opinion. Because when I got my ticket, a male officer check the date of my I765 receipt and he didn\'t say anything. But he did rejected a girl eariler becaue her receipt date is not early enough. I heard him told her to come in on July 2nd, which made me very nervous. But he didn\'t say anything about my case ...
Good luck to you!
