When applying for a UK study visa, some students will have a credibility interview. This is so UK Visas and Immigration (UKVI) can be sure that you are a genuine student.
The questions will be about you, your motivations for studying and your background. There is absolutely no need to be nervous about this interview, but it helps to be prepared. There are no right or wrong answers; just be enthusiastic, be relaxed, and above all, be yourself!
