Thank you for your reply. I do have confimation of delivery on 8/15. But my EAD application was submitted couple days after 485, does that cause the return of EAD application? Because somebody post after you in my previous poster said, because I filed 485 and EAD seperately. I am so confused. Do you have some offical link? It doesn't matter 180 or 340, I just want to get EAD ASAP. Since there is a job available for me. Do you think I should write and return everything to them now, or until I got offical 485 receipt. We filed at TSC at 8/10, do you think it will take long time for us to get receipt? And, sorry I have another question, if I resubmit EAD after offical 485 receipt, will it take less time for me to get EAD card, I heard 5 weeks, is that true? Thank you so much.
