I went to Arlington office on Wednesday, October 27th early in the morning around 7am. There were maybe 30 people already waiting in front of the building before me. Normally office opens at 7.30 if I am not mistaken. I was waiting not more than 15 minutes when immigration officer showed up and started asking people if there was anyone having an appointment. He came to me and asked the same question. I said I did not have any appointment and that I came for interim EAD. He told me that everyone has to have an appointment in order get an interim EAD.
I arrived at the Garden City DO at approximately 10:15 this morning. My interview was scheduled for 11:25, so I decided to try my luck and see if the security guards would allow me to get in early. They politely told me to come back at 11:00, so I dropped my fiancee off at Bloomingdale's at the Roosevelt Field Mall and drove back to the parking lot at 711 Stewart Avenue. I should mention that there is plenty of free parking available, so don't worry about where you can leave your vehicle.
