Without any information about what type of visa and from where youβre applying, start with a telephone call to your locationβs Visa Application Center. If your application is incomplete and youβve been unable to schedule an interview, contacting the Consulate may not be helpful. Be aware that some of these offices do not respond to emails or fax requests, as a matter of practice.
In the United States, the State Department lists U.S. Visa Contacts categorized by visa type, as well as an Embassy/Consulate locator.
