Hello! I have received the receipt of my I485 which has mentioned Preference Classification as "Family Based 2B". Initially my mom had filed I-130 when they were on Green Card so it was F2B category but about a year ago she got citizenship so I mailed them to change my case from F2B to F1 (Family Based 1) and I also have confirmation email from NVC. So should I worry about them mentioning Preference Classification as "Family Based 2B" or I need to call or send any other paperwork?
P.S: I have already attached a copy of I-130 and that acceptance letter with my I485 file.
