Hello,
We recently took out a PO Box for better mail security. We can still receive mail at our home address as well. I would like the mail regarding my husband's USCIS paperwork to be sent to the PO Box. I looked at the form AR-11 and it states no PO Boxes, and only to list a new physical address if you have moved. Since we haven't moved, do I need to fill out the AR-11? Or is just listing the PO box and the physical street address on page 2 of the I-751 OK that way? I didn't want to cause confusion in the system.
