Hi guys, I don't know if this is the right forum to ask, so if it's not, moderator, you can move it. Anyway, my Green Card arrived in March with a mistake. It was the date of my becoming a resident, so I didn't notice it until July. I sent the card back with the form to USCIS and I got a confirmation from USPS that the packet was received, but I haven't heard anything from USCIS. Should I expect NOA or case number or something? Has anyone else had this problem? Thanks in advance.

anyone?
