Now I am going to apply for my son to study in Britain, undergraduate course. How much do I need to deposit in the bank to apply for a visa to study in the UK? How long does it take to freeze?

Deposit about RMB 300,000 and freeze it for three months. Remember that these deposits must be deposited one month before the visa, and the existing ones are not accepted. At present, the UK requires a deposit 28 days before the visa application is submitted, which can be used as a financial guarantee for applying for a visa to study in the UK.
