More Detailed experience
Here is my experience
1. I got info pass appointment on July 02, for Jul 15 at 2:15 and 2:30 PM respectively for self and spouse (last ones for the day since, I have a toddler, did not want to take chances of going without an appointment).
2. Reached local USCIS center at Biscayne Blvd and 79th st at 2:10PM.
Parked at the $10 private lot West of the center (Attendant told us to go to the back of the building If I have an Approval notice, While going there signs indicated that for Approvals it would be section C at the back. Anyway reached the backside there were half a dozen people milling around with couple of security people at the small entrance. I showed the appointment letter the gaurd saw it and said the appointment is at 2:30 so you have to wait outside, for my wife he said she can go in but when he noticed the Approval notice in the hand. Asked us to go directly to the front and show the approval notice to the guard and not to bother about the info pass appointment.
Went to the front showed the approval notice to the security guard in front of the building, then to the security guard in between the double door entrance. Then Passed through the security check like the ones we have at the airports. Took the lift for 2nd floor, another guard saw the notice and asked us to place the notice in the second bin on the right while passing through the hallway at the right. On the left there was seating for more than 50 people. It was 2:15 when we took the seats. There were about 15 people waiting, I soon realized that those folks were not Employment based categories and were there for various reasons. They were being called in the front and being pictured etc.
After about 5 to 10 minutes my name was called from behind to the left. The cute lady greeted and asked for the passport and photos. Then she took some blue form put some plastic stencil kind of thing asked me to right index finger print and sign on both sides of the form. She told me I wouldn’t need the I94 she put it in the trash, put a red stamp in the passport dated and signed and said I would get the card in 4 – 6 months (it felt like she said 46 months) I did not bother for clarification, since I know it was a standard message. She asked me if my wife was also with me, I could send her in. I told her asked my wife to go in, she was also done in 2 minutes we were out of the building by 2:35Pm, out of Biscayne Area in another 10 minutes.
While going out I saw vacant coin parking meters and also noticed a towing guy was placing a wheel restraint on a few cars at the shopping area parking.
Overall everyone was pleasant and process was real quick.
