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.
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
My wife got FTJ IV visa stamped in her passport in Chennai. EB3 - PD 4/30/2001.
Below is the process, in her words, she went thru:
Medicals:
Called two days ahead for a 10.00 AM appointment with "Lister METROPOLIS Laboratory Research Center Pvt. Ltd" and a 4.00 PM appointment with "Dr. Mathai Thomas".
Flew in from Hyderabad to Chennai, had in-flight breakfast, took a taxi from airport to the Lab, 30 min ride.
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.
My wife and I had our passports stamped after a 6 hour ordeal that started at 8:30 a.m. and ended at 2:30 p.m. Here are some tips based on what we experienced,
1. For an 8:40 appointment, get there before 8 if at all possible. They were not checking appointment timings, so people with 9/10 a.m. appointments were ahead of us in the line. All they care is that you have an appointment for that day.
