The UK Student visa (formerly Tier 4) allows people to study at UK universities, colleges, and independent schools. The UK remains one of the world's top destinations for international education, with universities like Oxford, Cambridge, Imperial, UCL, and the London School of Economics attracting students from every country on earth.

Step one — your Confirmation of Acceptance for Studies (CAS)

Before you can apply for a UK Student visa, your university or college must issue you a Confirmation of Acceptance for Studies (CAS) number. The CAS is a unique reference number that your educational institution creates in the Home Office's sponsorship management system. It contains all the details of your course, your fees, and your start date.

You cannot apply for your visa until you have your CAS number. Most universities issue CAS numbers 4 to 6 weeks before the course start date, which means your visa application window is narrower than many students expect. Planning your financial documents, English test, and other requirements well in advance of the CAS issuance is essential to avoid a rushed application.

Financial requirements — the most common stumbling block

The financial requirement for a UK Student visa has two components: course fees for the first year, plus living costs for the duration of your studies (up to 9 months). The living cost allowance is currently £1,334 per month for students studying in London and £1,023 per month for students studying elsewhere. These amounts must be held in your account for 28 consecutive days before your visa application date.

The 28-day requirement is strict and specific. The funds must be in your name (or your parents' names if they are providing the funds, with an accompanying declaration). The balance must not drop below the required amount at any point during the 28 days. A single day where the balance falls short — even by a small amount — means the 28-day clock resets. Planning your bank balance around this requirement takes careful management.

English language requirements

Unless you are from an English-speaking country or your previous qualifications were taught in English, you will need to demonstrate English language proficiency. The most widely accepted test is IELTS Academic, with most universities requiring a minimum of 6.0 to 6.5 overall with no band below 5.5. Some universities and courses require higher scores.

Your CAS will specify the English language requirement your institution has accepted. If you have already taken an English test and your university has accepted the result, you do not necessarily need to provide the original test certificate with your visa application — your CAS reference covers this. However, you should have the certificate available in case the Home Office requests it.

Applying for your visa — timeline and process

You can apply for your UK Student visa up to 6 months before your course start date. Most students apply 2 to 3 months in advance. The application is made online through the UK Visas and Immigration (UKVI) system, and you will need to book a biometrics appointment at a Visa Application Centre in your country.

Processing times vary by country but are typically 3 weeks, though this can extend during peak periods (June to September when the academic year begins). If you need a decision faster, priority and super-priority services are available in many countries at additional cost. Check the UKVI website for current processing times in your specific country before deciding on your application timeline.

Graduate visa — staying after you graduate

One of the most significant changes to UK student immigration in recent years is the Graduate visa, introduced in 2021. After completing a degree-level or above qualification at a UK university, you can apply for a Graduate visa that allows you to stay and work in the UK for 2 years (3 years for PhD graduates) without needing a job offer or an employer sponsor.

The Graduate visa gives you an open work right — you can work for any employer, in any role, at any salary. This dramatically changes the calculation for international students considering the UK, because it gives you time to find a graduate-level job and then switch to a Skilled Worker visa without having to leave the country.

What to bring when you arrive in the UK

Your visa will be a vignette sticker in your passport if you are applying from outside the UK, valid for a short period (typically 90 days). After arriving, you must collect your Biometric Residence Permit (BRP) from a designated Post Office within 10 days. Your BRP is your actual visa document for the duration of your studies. Losing your BRP or failing to collect it promptly creates significant complications — report any issues to your university international student office immediately.
