Just wanted to submit my timeline. I sent my application within the suggested 150 days, they received my application on 6/6/16 and my biometrics appointment was scheduled on 7/16/16 for 8/5/16. My EAD expires on 10/26/16. When I received my notice for biometrics appointment, there was a separate envelope (Notice of Action) with the information for the USCIS online account. I noticed that on this second envelope received, the form had a priority date of 5/31/16, for those who have received the USCIS online account information, what is the priority date signify?
