Until the end of July 2003, students who are not visa nationals could choose whether to apply for entry clearance or not. Students would consider this if their course lasted for six months or less, if they were applying as a prospective student or they were bringing their family with them. Students who chose this option had to satisfy the Immigration Officer at the port of entry that they fulfilled the Immigration Rules for students. Entry clearances that are issued to people who are not visa nationals are called entry certificates- rather than visas. There is a charge for the application.
