Visa credibility interviews
You may be required to attend a credibility interview to ensure that you comply with the UK’s immigration rules. The purpose is for an Entry Clearance Officer (ECO) to establish that you are a genuine student. You need to show you are serious, and that you have good knowledge of your chosen university and course. If you have done your research, the interview is nothing to worry about. The process is just designed to filter out people who are planning to use a student visa to work or holiday in the UK.
