The article explains what a UK credibility interview is and why international students may have to take it when applying to study in the UK: it’s an interview used by universities or UK Visas and Immigration to check that a student is a genuine applicant who truly intends to study, understands their chosen course and university, can explain their academic background, funding plans, English ability, and future goals, and is not using the student visa for other purposes; the blog also outlines the difference between a Pre-CAS interview (done by the university) and a Credibility Interview (done for the visa), along with common questions and basic preparation tips.
