Adult Student Visa (Tier 4)

What is the Adult Student visa?

The Student visa (often still called Tier 4) is the main UK study route for applicants aged 16 or over. You need a Confirmation of Acceptance for Studies (CAS) from a licensed student sponsor and must meet academic progression, English, and financial requirements under the Immigration Rules.

Who may qualify?

You may qualify if you have an unconditional offer from a licensed education provider, can show the required funds for fees and living costs (unless exempt), meet the English language level for your course, and genuinely intend to study. Age, course level, and previous UK study history all affect eligibility.

Key conditions once granted

Permission is usually tied to your course dates. Work rights depend on your course level and sponsor type — typically limited hours in term time for degree-level study. You must keep your sponsor informed of changes and may need to apply for an extension if your course continues.

CAS and academic evidence

Your licensed sponsor issues a CAS with your course details, fees, and any ATAS or academic progression notes. Keep your offer letter, qualifications used for the offer, and any credibility interview notes aligned with the CAS.

Maintenance funds

Unless an exemption applies (for example certain scholarship or differential fee arrangements), you usually need to show course fees plus living costs held for the required period in an acceptable account. Bank statements must meet Home Office format rules.

English language and TB

Many degree-level courses require CEFR B2 English via an approved test, GCSE/A-level English, or a degree taught in English. Applicants from listed countries may also need a tuberculosis certificate from an approved clinic.

How to apply

Apply online using your CAS reference, pay the Immigration Health Surcharge and visa fee, then complete biometrics or an ID check. Applications from outside the UK should be timed so you arrive no earlier than the permitted window before your course start date. We prepare representations and check evidence before you submit.

Costs & processing time

Home Office Student visa fees and the Immigration Health Surcharge apply per person and change periodically; as of 2026 you should confirm current amounts on GOV.UK. Priority services may be available in some locations. Our legal fees depend on complexity — we confirm costs in your free consultation.

Common reasons applications are refused

• CAS expired, incorrect, or not used within the validity period

• Funds held for too short a period or in an unacceptable format

• English language evidence not at the required level or from an unapproved provider

• Credibility concerns about genuine intention to study

• Previous immigration breaches or unexplained gaps in study history
