Hi there, good timing! USPS informed delivery email showed that 2 pieces of mail coming in later today from USCIS. Probably one is NOA and the other one is online access code, so that I can add the case to my USCIS account. They also scheduled me for bio, so once I can add my case online I should be able to download the bio appointment letter.
online updates said they received my packet on 2/13, but the NOA is dated 2/16, my card was charged 2/15.
did you receive you case number?
