Got EAD from St. Louis local office Friday
I got my EAD from St. Louis local office with I-485 receipt notice. They accept application forms everyday, however they only issue EAD cards in Wed, Fri. from 12:00- 2:30 pm. The other thing I want to mention here is that you don't have to bring your pictures, they will take for you when they issue you the card without extra fee.
