The UK has a points-based visa system, which is designed to be objective and transparent. To apply for a student visa, you need to gain 40 points. This includes 30 points for a “confirmation of acceptance for studies” from the university, college or school where you want to study.
Your chosen place of study must be on the “register of sponsors” kept by the UKBA. This register is designed to give you peace of mind that you are applying to join a bona fide institution.
