How many days does it take to issue a UK visa?

Legal subjectivity:

It generally takes 15 days to process a UK visa application. A UK visit visa is valid for six months and cannot be extended. If you plan to study a one-year preparatory course, followed by a three-year bachelor's degree program after one year, your visa will only be valid for the first year. However, with an unconditional offer of admission to a three-year course, the visa is valid for 3 years. The law is objective:

Article 9 of the "Exit and Entry Administration Law of the People's Republic of China" Chinese citizens entering and exiting the country must apply for a passport or other travel documents in accordance with the law. Chinese citizens traveling to other countries or regions also need to obtain a visa or other entry permit from the country of destination. However, this does not apply unless the Chinese government has signed a mutual visa exemption agreement with the governments of other countries or if the Ministry of Public Security or the Ministry of Foreign Affairs provides otherwise. Chinese citizens who enter or exit the country as seafarers or work on foreign ships must apply for a seafarer's certificate in accordance with the law.
