I am currently in the last stage of getting my employment based Green Card (My I-485 has been filed for). I received an EAD valid for a year. I filed for an extension of the EAD some 120 days or so prior to its expiry. USCIS sent in a RFE (Request For Evidence) some 80 days after my filing. I sent in the requested evidence within 10 days of the RFE. When my current EAD expired, I went to the Detroit USCIS office to get an interim EAD. After waiting for over 3 hours, the USCIS rep. took less than 10 minutes to review all my documents and refused to issue me an interim EAD.
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.
I reached the office at 7.30 am on 12/11 (91st day after RD on I-765 notice) and found that I was the only one out there. Since it was 8 deg in the morning, this didnt come as a surprise to me
The office opened at 8 and I was given a token when I entered. I was called in about 20 minutes.
I took the following documents with me:
1. Copy of I-765 notice
2. Copy of I-485 notice
3. Filled out new I-765 form
