Complete Guide to UK Student Visa (Tier 4) in 2025

Everything international students need to know about applying for a UK Student Visa in 2025, including documents required, fees, processing time, and the CAS process.

What is the UK Student Visa?

The UK Student Visa (formerly known as the Tier 4 visa) allows international students to study at a licensed UK educational institution. This comprehensive guide covers everything you need to know to successfully apply.

Who Needs a Student Visa?

You need a UK Student Visa if you are a citizen of a country outside the UK and want to study in the UK for more than 6 months. EU/EEA and Swiss citizens now also require a Student Visa following Brexit.

Key Requirements

Before applying, ensure you have:

A confirmed place (CAS) – Your university must issue a Confirmation of Acceptance for Studies number.

English language proficiency – IELTS Academic score of 5.5–7.0 depending on your institution.

Financial evidence – Proof you can cover tuition fees and at least £1,334/month (London) or £1,023/month (outside London) in living costs for up to 9 months.

Valid passport – Your passport must be valid for the duration of your study.

Tuberculosis (TB) test – Required for students from certain countries.

The CAS Process

Your Confirmation of Acceptance for Studies (CAS) is issued by your university once they have confirmed your place. The CAS number is a unique reference that you need for your visa application.

Application fee: £363

Immigration Health Surcharge (IHS): £776 per year of study

Processing Time
