Recently I have been to Baltimore District Office to collect my interim EAD, I was told that if INS Processing Center(Vermont) requested some additional documentation, that requested documentation should be sent to Vermont(that information should be updated in INS database), then only they can issue interim EAD. They are taking 30 days to issue Interim EAD.
I walked in to the Detroit USCIS Center on Monday Sept 9th 2003 at 11:30pm. They gave me the waiting number & gave me an application form for Employment Authorization. At around 3:00 pm the duty officer wanted receipt notices (over 90-day proof), the original I-765 application, I-94 & driving licence (proof of picture ID). She asked me to get photo copies of each of these documents, which I got it immediately for her. After an hour someone called my name and took my picture and provided the card good for 6 months.
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.
On the 90th day, I make an appointment. The earliest day on infopass is 5 days later on Friday, so I make that appointment, and print out the sheet confirmation with the barcode.

On Friday
-------------------------
I went to the line at 10:00am for my 10:30 appointment. The guy at the door says you can't come in yet, come back 15 minutes later. That means even if you come really early before your appointment it is pointless. It is best to come 15 min before.
