Hello, I filed F1 OPT based EAD, then filed I485 (as dependent). Since the EAD took several months to approval, before I got the EAD card, my I485 has filed. So now I have 2 alien numbers, one is from the approval of Opt based EAD, another is from I485 receipt. Anybody has similiar experience? Will cause any trouble in the future (I485)? how can I explain to INS?
