It's been 82 days since I applied for my EAD (post-OPT) to the USCIS and my case is still not approved. I have a job offer that starts on my 90th day and I've tried expediting with no luck. However, I am very confused now. My lease at the current address ends in 15 more days, and I'll be moving to a new address in a week or so. How long does it take for USCIS to update their systems if I submit a request to change my address? I don't want the EAD to be delayed more because of an address update, at the same time, if my card comes to my current address after 15 days and gets returned things will be a mess. Any suggestions on whether I should wait or update my address right now?
