“Case Was Received”on your I-566 · A, G or NATO status changes


USCIS has an I-566 record for an A, G or NATO request, such as work permission for a diplomat's dependent or a change into or out of that status. The I-566 is usually sent through the State Department or the international organization, which certifies it first. Keep the receipt with your mission or organization's records.
