How long is a group tourist visa generally valid in the UK?

If you are in a group tour, as long as the materials you provide are true and reliable, you don't have to worry. The required materials are as follows: 1. Fill in the personal information form and take 4 photos (2-inch color passport photos taken within half a year, bareheaded on white background, black and white photos and remake photos are not required, and the size is 35mm*45mm). I signed the English form myself in England. Two business cards. (Chinese and English) 3. Personal passport is valid for 5 years (valid for more than 6 months, the last page of the passport must be signed by myself), and all guests who cancel the old passport must provide it. If the existing passport is really lost and reissued, the certificate of loss reporting from the Public Security Bureau must be provided, and the old passport will not be extended. Since there is no exit record on the personal passport, you must provide previous exit records: including official passport, one-time travel passport for Southeast Asia, Hong Kong and Macao pass, or photos taken in front of famous scenic spots. Pay attention to two consecutive blank passport pages in your passport.
