You are at the Official Nonimmigrant (temporary) Visa Information and Appointment website for the U.S. Embassy in United Kingdom.
The online visa application form DS-160 must be signed and transmitted at least 48 hours prior to the interview otherwise we will not be able to process your application on the day. The form is available at https://ceac.state.gov/genniv.
If, when completing the online visa application form DS-160 you have selected a location that is different to the one at which you will apply for the visa, you are required to complete a new DS-160 prior to your interview. For example, if you are applying for a visa in London, you must select England, London; if applying in Belfast, you must select N. Ireland, Belfast.
If you are required to complete a new DS-160, there is no requirement that you change the DS-160 number in the appointment booking system at https://ais.usvisa-info.com/en-gb.
