Interim EAD experience at Detroit
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 have used this firm for a number of years for H-1B visas. They are extremely professional and organized. And most recently I had an employee require H-1B status quickly due to a student visa heading toward expiration. We did the premium process through this group and the approval came back in much less than the 15 day turnaround time. That in itself should tell you everything you need to know. If you don't hire this group, you are doing yourself a disservice.
