Great Info here! Thanks mom!That's the number listed as your USCIS# on your EAD card.
I currently have EAD card so the uscis#is my ARN, that's for sure.
My wife, used to be F1 (currently she is H1) OPT and with EAD card as well.
So for the question in DS260"Were you issued an Alien Registration Number by the Department of Homeland Security?
Does she have to put the uscis# on her EAD card here? (Although she is H1 now and not using that EAD anymore)
