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).
First of all, I wanted to thank all the members of this forum for their insight and support. This road did not feel as lonely as we all traveled it together.
When an I-485 is accepted at the Service Center, requests for FD-258 FBI fingerprint checks, fingerprint fees, and G-325A consular background checks are made by USCIS. Responses to these requests come back to USCIS and must be matched up with the appropriate files held in staging. File Maintenance "file connects" these responses to the corresponding files.
