A letter of acceptance on the course - Your approved education provider will give you an acceptance letter (CAS) and a visa letter which are official and unconditional offers of a place on a course of study. The visa letter must be issued no more than six months before you apply. The applications where the visa letters are older than six months will be refused.
Proof of funds - The money you need to show covers your course fees for your first year of study and living costs for up to a maximum of nine months. The amount you will need depends on whether you are applying as a child or adult and also whether you will be studying in or out of London. You must show that you have held the money for at least 28 days. The end of that 28 day period must not be more than one month before the date of your application.
