Immigrant Visa Processing - The National Visa Center (NVC)

After an immigrant petition filed in the United States is approved by USCIS, it is forwarded to the National Visa Center (NVC) for processing. NVC plays an important role in the next steps of the immigrant visa process by providing instructions to petitioners, sponsors, and visa applicants; reviewing required Affidavit of Support forms from sponsors; and receiving fees, application forms, and other required documents from visa applicants. For numerically limited family preference petitions, NVC contacts the petitioner once the petition’s priority date is about to become current
