To apply for a UK visa, you’ll generally need to apply online, pay the required fee, and book an appointment at a Visa Application Centre (VAC). You’ll then need to submit your application, supporting documents, and provide biometrics (fingerprints and photograph) at the VAC. Depending on your nationality and the type of visa, you may also need to obtain an Electronic Travel Authorisation (ETA).
