Applicants answer the questions asked in an interview for a U.S. visa by providing documented evidence of any needed information, according to the U.S. Department of State. Any spouse or qualifying unmarried children under 21 accompanying the applicant to the United States must participate in the interview and provide documentation.
Prior to their interview for a visa at a U.S. embassy or consulate, applicants must complete a medical examination and bring the sealed results of the examination to the interview, according to the U.S. Department of State. Applicants must bring originals and photocopies of all required documents as well as certified English translations of any documents not written in English or in the language of the country where the interview is held. Required documents for the applicant and each accompanying person include the appointment letter for the interview from the National Visa Center, passports valid for at least six months, color photographs, birth certificates and evidence of financial support. Other necessary documentation to answer specific questions may include a marriage certificate, a divorce certificate, police certificate, military records, and court or prison records.
If applicants do not bring all required documentation to the interview, their visa may be delayed or denied, according to the U.S. Department of State. Original documents are returned at the conclusion of the interview, but the photocopies are kept. Applicants are urged not to make any permanent financial commitments, such as the sale of property, until they learn of the interview results and receive their visas.
