How UK pre-CAS and UKVI credibility interviews work for Bangladeshi students, the most common questions by theme, conduct rules, preparation steps and mistakes to avoid.
A UK credibility interview is a short interview, usually online, that checks whether you are a genuine student who understands your course, can afford your studies and intends to study in the UK. Bangladeshi students can face two kinds: a pre-CAS interview run by the university before it issues your CAS, and a UKVI interview run by the Home Office after you apply for your Student visa. Questions usually cover your course, your choice of university and the UK, your academic history and any study gap, your finances, your accommodation and your plans after graduation, and they are asked in English without an interpreter.
This guide explains how both interviews work, the most common UK credibility interview questions, how to prepare, and the mistakes that can cost you a CAS or a visa.
Information was checked on GOV.UK and official university websites in October 2026. Interview formats differ by university and can change, so follow the instructions in your own interview invitation.
Key Takeaways
The Immigration Rules require every Student visa applicant to be a genuine student.
Many universities interview applicants from Bangladesh before issuing a CAS, often through a recorded or automated online system.
Home Office guidance says caseworkers must not refuse an applicant on genuineness grounds without interviewing them, except in limited cases.
The Home Office will refuse an applicant who cannot show the required English level without an interpreter.
Missing a UKVI interview without a good reason can lead to refusal, and failing a pre-CAS interview can mean no CAS.
Honest, specific answers that match your SOP, documents and finances matter more than memorised scripts.
What Is a UK Credibility Interview?
Under Appendix Student (ST 5.1), a Student visa applicant must be a genuine student. Universities also have a duty under the student sponsor guidance to do all they can to make sure the students they sponsor are genuine, and the guidance mentions interviewing students as one way to do this.
1. University pre-CAS interview
Held after you accept an offer and usually after you pay a deposit, but before the university issues your CAS. Formats vary:
Recorded or automated video: you answer questions on screen within a time limit, often through a platform such as CAS Shield.
Live video interview: through Microsoft Teams or a similar platform, typically 20 minutes to an hour.
Questionnaire: some universities, such as Teesside, use a credibility questionnaire as part of the CAS decision.
Some universities specifically list Bangladesh among the countries whose applicants must complete a pre-CAS interview. For example, Birmingham City University lists Bangladesh in its automated pre-CAS interview process (BCU CAS page). If you do not pass, the university may refuse to issue a CAS. Northumbria, for example, says applicants who answer unsatisfactorily will not be issued a CAS (Northumbria credibility interviews).
2. UKVI (Home Office) interview
After you submit your visa application, the Home Office may invite you to an interview. The Student caseworker guidance says interviews can be arranged in different ways, including by telephone or at a set time and place; universities report they are often by video link. Caseworkers consider factors such as:
your immigration history in the UK and other countries
your education history and your study and post-study plans
your personal and financial circumstances
the qualification, course provider and any agent you used
your English language ability
whether "pull factors", such as the ease of working during or after the course, were the main reason for your choice
If you do not attend without an acceptable reason, the guidance says the application must be refused. UKCISA also advises checking your junk email folder for invitations (UKCISA).
Common UK Credibility Interview Questions
The questions below reflect the themes universities publish in their interview guidance. Exact wording varies, and automated interviews may include random or unrelated questions to check spontaneous English.

How long is the course, and when does it start?
Name some modules you will study and explain why they interest you.
How will you be assessed?
How does this course connect to your previous studies or work?
About your university and the UK
Why did you choose this university?
Which other universities or countries did you consider, and why not them?
Why do you want to study in the UK instead of Bangladesh?
Where is the university located, and what do you know about the city?
About your academic history

What does your sponsor do, and what is the source of the money?
How much is your tuition fee, and how much have you paid?
How much money do you need to show for your visa?
How will you pay for the rest of the course?
Know your own financial documents well. Read our guide to bank statements and financial proof.
About accommodation and life in the UK
Where will you live, and how much will it cost?
How many hours are you allowed to work during term time?
What conditions apply to your Student visa?
About your future plans
What will you do after you finish your course?
How will this degree help your career in Bangladesh?
What kind of employers or roles are you aiming for?
About your immigration history
Have you visited or studied in the UK or another country before?
Have you ever been refused a visa? If so, why?
Do you have family members in the UK?
How to Answer Well
Be specific: mention real modules, the city, fees and your career goals instead of general praise.
Be consistent: your answers should match your SOP, CAS, application form and financial documents. See our SOP guide.
Focus on study: make clear that the course and your career are the main reasons for your choice, not work opportunities.
Be honest: if you do not know something, say so politely rather than inventing an answer. Disclose previous refusals when asked.
Speak naturally: memorised answers often sound scripted, and some universities treat reading from notes as a red flag.
Technical and Conduct Rules
Universities publish rules such as these for online interviews:
Have your original passport ready, as your identity may be checked on camera.
Sit alone in a quiet, well-lit room. Some universities may ask you to show the room.
Use a stable internet connection and a working camera and microphone.
Do not use notes, scripts, websites or AI tools, and do not allow anyone to help you. Several universities say this can lead to automatic rejection.
Answer in English. The Home Office states it will refuse applicants who cannot show the required English level without an interpreter.
Report technical problems immediately, as retake rules are strict at many universities.
Step-by-Step Preparation Plan
Study your course page: modules, length, assessment, fees and start date.
Research the university and city: location, accommodation options and costs.
Review your documents: SOP, CAS details (if issued), transcripts and financial evidence.
Prepare your story: how your past studies or work lead to this course and to your future career in Bangladesh.
Practise speaking: record yourself answering questions in English within one to two minutes.
Do a mock interview: practise with someone who can give honest feedback on clarity and confidence.
Check your set-up: test your device, internet and room before the interview.

Common Mistakes to Avoid
Not knowing basic course details such as modules or course length.
Saying you chose the UK mainly to work or settle.
Being unable to explain who is funding you or where the money came from.
Giving answers that contradict your SOP or documents.
Reading from notes or having someone help you during the interview.
Hiding a previous visa refusal.
Missing the interview invitation in your email.

Can I retake a failed pre-CAS interview?
It depends on the university. Some allow one retake in borderline cases, while others allow only one attempt.
