They open at 9am I arrived at 815. There are 2 lines. North- if you need a new or replacement social security card. South- if you need anything else. They offer applications before the doors open. Take advantage of that and have it filled out before going in. I was 20th in line but the 4th person in line to have the application done so I was bumped to the front of the line. It took about 5 min for the lady to enter my info and print out a receipt for me.
