1) Is it usual for the USCIS to send the receipt notice to your residence address as opposed to the mailing address that I provided? We're moving in a few weeks, so as I will be submitting an AR-11 anyway (and will file a change of address form with the post office) so it probably doesn't matter. But just curious - we have a PO box address, and it seemed logical to include that as a mailing address rather than our soon-to-be "ex" apartment.
2) What's a good estimate on the wait time for NOA1 from VSC?
