Got there at 6am and there were already about 80 people ahead of us.
At 6:15 they started handing out tickets. At 7:30 we had ours.
Went inside to sit down and at 7:45 our number came up. Handed over copies of the I-765 and I-485 receipt notices (it speeds up things if they do not have to make the copies) and newly filled out I-765s (they want them).
Recently USCIS erroneously scheduled some customers for more than one Application Support Center (ASC) biometric appointment (Form I-797C).
If you have already attended an ASC biometric appointment, and received a second appointment notice for the same application type, please call the National Customer Service Center at 1-800-375-5283 (TTY for hearing impaired: 1-800-767-1833) to confirm that you do not need to return to the ASC to have biometrics collected again.
