If your visa has been approved, you will be informed how and when your passport and visa will be returned to you. In general, a passport with a visa will be returned by mail within seven to ten days from an interview.
Normally, you will also receive a sealed packet containing documents. However, if “IV Docs in CCD” is annotated in your immigrant visa, it means that your visa is a digitalized visa, and you will only receive your passport from us. Under rare circumstances, you will still receive a sealed packet containing documents along with your passport even if you your visa is annotated. When you receive a packet, do not open the sealed packet, and present it to the U.S. Customs and Border Protection at a port-of-entry upon your arrival in the United States.
