The UK CAS and credibility interview: the questions, and how to answer from Nepal.
Before a UK university issues your CAS, it usually checks you're a genuine student in a credibility (pre-CAS) interview, often 10 to 20 minutes on video. Expect questions on why this course and university, why the UK, how your studies connect to your past and future, who pays and how much it costs, and where you'll live. Answer in your own words with facts from your documents; rehearsed paragraphs are the fastest way to fail.
The short version
- The pre-CAS interview is the university checking you before it vouches for you to UKVI. Failing it means no CAS.
- Questions cover five things: the course, the university, the UK, your money, and your plans after.
- Know your numbers: tuition, deposit paid, living costs, who pays, and where the money sits for the 28 days.
- Know your course: modules, length, start date, campus, city. Vague answers about 'quality education' fail.
- UKVI can also interview you after you apply. Same rules: short, specific, true.
Why the university interviews you
A UK university that sponsors students has to keep its refusal rate low, or it risks losing its licence. So before it issues a CAS (Confirmation of Acceptance for Studies), it checks you itself. The pre-CAS or credibility interview is that check. For you it’s a rehearsal for UKVI, and a second chance to spot a weak answer before it’s on a visa file.
The questions, grouped
| Area | Questions you’ll hear | What a strong answer has |
|---|---|---|
| The course | Why this course? Name three modules. How long is it? When does it start? | Module names, length, start date, and a link to your past |
| The university | Why this university? Which campus? What city? | One or two specific reasons: a module, a placement year, the fee, the location |
| The UK | Why the UK and not Nepal, Australia or Canada? | A real comparison: length, cost, the course’s content |
| Your past | What did you study? Any gap? What work have you done? | Dates and roles that match your documents |
| Money | What’s the tuition? How much is paid? Who pays? From what income? | Exact figures; the sponsor’s job or business |
| Living | Where will you live? How much is rent? | A realistic figure for the city, and a plan |
| After | What will you do after graduating? | A role, a sector, and where |
Answers that work, and why
“Why this course?” (an IT graduate applying for an MSc in Data Science)
“I finished a BSc CSIT at Tribhuvan University in 2024 and have worked for a year as a junior developer in Kathmandu, mostly on reporting tools. The MSc’s modules in machine learning and data engineering are the skills our team keeps hiring for.”
“Why this university?”
“It has a placement-year option, the fee is £16,500 against £22,000 for my second choice, and Leeds is cheaper to live in than London.”
“Who’s paying?”
“My father. He runs a hardware business in Butwal with PAN registration and three years of tax clearance. The money for the first year, about Rs 48 lakh, has been in his account since July.”
“What will you do after?”
“I’d like to work in the UK on the Graduate visa in a data role, then use that experience either there or with a Nepali fintech company.”
Notice what each one has: dates, names, amounts, a reason. None of them praise the UK.
The mistakes that fail interviews
- Reading or reciting. Interviewers can tell, and it reads as coached.
- Not knowing your own numbers. Tuition, deposit, the living-cost figure, who pays.
- Not knowing your course. If you can’t name a module, why are you paying £18,000 for it?
- A course that doesn’t follow from your past, with no reason given.
- “I want to settle in the UK” as the main reason. Wanting to work on the Graduate visa is fine; making settlement the plan is not what the interview is checking for.
- Contradicting your documents. If your statement says you worked at a bank and your CV says a school, the interview will find it.
How to prepare in a week
| Day | What to do |
|---|---|
| 1 | Read the course page: modules, length, assessments, start date, campus |
| 2 | Write your numbers on one card: tuition, deposit paid, living costs, who pays, income |
| 3 | Write one-line answers to the seven areas above, in your own words |
| 4 | Practise aloud with someone who’ll interrupt you |
| 5 | A mock interview on video with a counsellor |
| 6 | Fix the answers that sounded vague |
| 7 | A second mock, then rest |
We run two mock interviews for every UK student before the university’s. Students who’d never spoken to an interviewer on video find the second one much calmer than the first.
On the day
- A quiet room, good light, your passport within reach. Some universities check it on camera.
- Test the link 30 minutes before.
- Look at the camera, not your notes.
- If you didn’t hear a question, ask. That’s better than answering the wrong one.
- If you don’t know something, say so honestly, then say how you’d find out.
If UKVI calls you too
UKVI can interview you after you apply, usually on video. The questions are similar. Answer the same way you did with the university; officers compare your answers with your CAS and documents.
