Most EU/EEA, US, Canadian, Australian, Japanese and Gulf visitors can enter the UK visa-free for up to 6 months but must hold a UK Electronic Travel Authorisation (ETA, about GBP 16) before travel if they do not already hold a UK visa. Nationals of visa-required countries (e.g. China, India, Turkey, South Africa, Russia) need a Standard Visitor Visa (GBP 127, apply around 3–4 weeks ahead, ideally up to 3 months).
