Today I had my passport stamped @ Chicago office at about 7.50 AM. I went and stood in the line @ 6.40 AM. The line was not that big. Around 30-35 people were ahead of me. They let us in at 7.00 AM. After getting inside, on 2nd floor, each person gets a ticket with a number and is asked to wait in the hall.
For passport stamping, the ticket number starts with 601. Mine was 603, but it took about 20 minutes for my turn. The I.O. asked for the approval letter, passpost and one form of ID. He took my EAD and kept it, stamped the passport and advised that when I am travalling I must carry the approval letter as well. He gave the reason for carrying the approval letter being the systems at some airports are not updated and they may not have the records of my I-485 approval.
I had my AP as well but he did not ask it back. No photograph was required either. The IO took about 2-3 minutes in the process and I was on my way to work.
