I want to ask, how old is the child to let him study in Britain?

See if your parents have any plans to accompany you. /kloc-children under 0/2 can apply for visa escort. If you don't have time to accompany you, wait until the children are older, or you can consult Mr. Chai about studying abroad. They have been focusing on studying abroad for younger students for more than 20 years, and can provide tailor-made all-round study abroad services for younger students with a systematic early warning system, including picking up the plane and sending it to the police station for formalities, opening a bank account, registering a school and so on.
