Those traveling to American Missions abroad are often in search of a US Embassy or US Consulate that can assist in visa matters and other proceedings which must be carried out by US government personnel. Such activities include, but are not limited to: Consular Report of Birth Abroad issuance, US passport renewal, addition of visa pages, and notarial services. Generally, the American Citizen Services Section of a United States Consulate can assist in these matters. Those with business at an American Citizen Services post are encouraged to check the official website of the US Embassy in order to ascertain if appointments can be scheduled online. This can greatly streamline processing of requests as ACS officers can anticipate customer requests and prepare to provide appropriate services.

Those seeking a visa to the United States of America often require a visa interview in order to complete the adjudication process. Those seeking a visa interview are well advised to contact the local post or check the official website for details about appointment scheduling. Usually the protocols for non-immigrant visa interview appointments are different than the protocols for setting immigrant visa interview appointments (for purposes of visa processing, generally the K1 visa is considered to be an immigrant visa).
