What the UK Student visa needs from Indian students: CAS, English evidence, funds, TB test, fees, processing times and the most common refusal reasons.

10 min read · Last checked 22 August 2026

The answer in 60 seconds

  • You need a CAS from a licensed student sponsor, English language evidence, enough money held for the required period, and a TB test certificate if you are applying from India.
  • You can usually apply up to six months before the course starts from outside the UK.
  • The main refusal causes are financial evidence errors, credibility interview answers, and documents that do not match the CAS.

The document set

Prepare these before you start the online form, because the form asks for details that must match the documents exactly.

  • Valid passport with a blank page.
  • CAS number and the details listed on the CAS.
  • English language qualification (usually a SELT, unless your university assesses you).
  • Financial evidence covering fees and living costs.
  • TB test certificate from an approved clinic in India.
  • ATAS certificate for certain sensitive subjects.
  • Parental consent and birth certificate if using a parent's funds.

The timeline that works

Working backwards from a September intake: accept the offer and pay the deposit by June, get the CAS in June–July, complete the 28-day fund hold by mid-July, book the TB test and biometrics, then submit in late July.

Leave four clear weeks of buffer before your course start date, and more if you need a new passport.

The credibility interview

Many Indian applicants are asked a short credibility interview. It is not a test of English perfection — it checks that you know your course, your university, your funding and your plans afterwards.

  • Know your modules, course length and tuition fee.
  • Be able to explain why this university and this city.
  • Explain who is funding you and how they earn that money.

Common mistakes

  • A financial statement dated more than 31 days before submission.
  • Course details on the form that do not match the CAS.
  • Booking the TB test too late and delaying biometrics.
  • Vague interview answers about funding or post-study plans.
