I want to go to England around August 15. Can I make an appointment for a visa at the end of June?

At present, you only need to deposit 1 month visa deposit in the UK under your personal name, but only if it is no longer allowed under your parents' personal name. The deposit certificate still needs to be issued. It is uncertain whether the Korean passbook can be recognized by the visa office of the British Embassy in China. Even if it is recognized, it is not particularly convincing. It is certain to translate it into English.
