My wife is currently a US green card holder. We just moved and she filed her change of address online, as per USCIS requirements to notify them within 10 days of moving. However, the online change of address form requests a receipt number for a case. Her case is closed, because she was issues her green card. However, the form indicates that applications associated with a closed case may be declined. She submitted the form with the receipt number for her closed case. Is this going to be a problem? Should she resubmit the form selecting the option that she doesn’t have a receipt number?
