My wife's EAD application experience
My wife's EAD application is pending at VSC for more than 4 months now. On 91st day (Which happened to be a Wednesday), we reached Arlington office at 1.45pm. They asked us to wait in a room, after a while someone picked up her receipt and gave her a form to fill out. After 30 minutes they asked her to wait in another room after verifying the payment info. She was done by 3.15pm, so I should say it was a painless and quick procedure. She was issued EAD valid for one year.
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.
