I applied for post-grad OPT on Feb 14, my card was approved on May 26. I never received my card and I decided to go ahead and go to get interim EAD. Handed in my infopass appointment sheet at the door of 26 Federal Plaza and was directed to the 3rd floor. At 3rd floor, an officer scanned my sheet and my I797 Notice to make sure its more than 90 days since I first applied for EAD. Then he gave me an N number and directed me to the 9 floor. At the 9 floor, my number was called. Unforunately, I need a proof of residence in new york.
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.
