On June 1, 2020, the National Visa Center will no longer accept or respond to inquiries through the mail. The National Visa Center claims to have modernized the way they pre-process visa applications. This has allowed NVC to streamline services to case parties and to U.S. Embassies and Consulates. Elimination of paper correspondence is the next step in this modernization. This change will further help them streamline and provide better services for all involved.
Any unsolicited mail post-marked June 1, 2020, or later will not receive a response and will be destroyed. You will need to submit all your inquires through the Public Inquiry Form at https://nvc.state.gov/inquiry.
