UK Student Visa Guide

The UK Student Visa, Explained

Most international students coming to study in the UK apply for a Student visa. It’s issued by UK Visas and Immigration (UKVI), and the application is completed through the UK government’s own official website, not through a university, an agent, or a recruitment platform. If you have been told you need a “Tier 4” visa, that is the route’s former name — it was replaced, and guidance still using it is out of date.

This page explains how the route is structured and what it generally asks for, so you know what you are walking into. It is not immigration advice, and the figures that matter — financial thresholds, fees, processing times — change. For those, gov.uk is the only source worth trusting, including over this page.

What a Student Visa Application Generally Needs

While exact requirements can change and always depend on your individual circumstances, a Student visa application typically involves:

• A valid CAS (Confirmation of Acceptance for Studies) from your university, confirming your offer and course details.
• Proof of your finances, showing you can cover your course fees and living costs.
• English language proficiency evidence, in the form the Home Office accepts.
• A valid passport, and depending on your circumstances, other supporting documents.

Because requirements can vary by nationality and individual situation, the UK government’s own website is the accurate, current source for exactly what you’ll need, not a general guide like this one.

The order things have to happen in

This is the part most applicants get wrong, and it costs them intakes rather than money.

1. Offer from the university.
2. Conditions met — academic documents, English evidence, anything else the offer specified.
3. Deposit paid, where the university requires one.
4. CAS issued. The university will not issue this until steps 2 and 3 are genuinely complete.
5. Visa application submitted, using the CAS.
6. Biometrics and decision.

You cannot start the visa application before you hold a CAS. That single dependency is why document delays early on turn into missed intakes later — every day lost at step 2 is a day pushed onto step 5, and step 6 is not something anyone can accelerate for you.

If you are working to a tight timeline, our January intake guide sets out how the same sequence compresses for a winter start.

The financial requirement, in principle

You are asked to show that you can pay your course fees and support yourself. Two things about how this is assessed catch people out:

The money usually has to have been held for a continuous period before you apply, rather than appearing in the account the week before. A sudden large deposit is the single most common reason financial evidence is questioned.

Where you will study changes the amount. Living-cost requirements are set differently for London and for the rest of the UK, which is one more reason location affects affordability well beyond rent — a point our guide to affordable UK universities covers in more detail.

We are deliberately not printing the figures here. They are reviewed and changed, and a number copied into a guide is the kind of thing that quietly ruins an application a year later. Check gov.uk.

Common reasons applications run into trouble

Most problems are procedural rather than substantive — which is good news, because procedural problems are preventable:

• Financial evidence that doesn’t meet the format required — wrong document type, wrong date range, missing bank letterhead, or funds not held long enough.
• Name or date mismatches between passport, transcripts and CAS. These look trivial and are not.
• Documents not translated where a certified translation is required.
• CAS details not matching the application — course, start date or fees recorded differently.
• Applying too late for the course start date, leaving no room for a normal processing time.
• Incomplete supporting documents, particularly where a country-specific requirement applies.

The pattern is consistent: applications fail on paperwork, not on merit. That is exactly the stage where getting your documents reviewed before anyone relies on them is worth the effort.

Working while you study

One of the most common questions, and one where guessing is expensive.

The Student visa permits limited paid work during term time, with more allowed during official vacation periods. The exact limit depends on your course level and is stated on your visa. Our guide to how many hours a student can work in the UK covers the detail, including what counts as term time and what is excluded. Some categories of work are excluded regardless — self-employment and professional sportsperson roles among them.

Three points worth internalising:

• Your visa states your own conditions. Do not rely on what a friend on a different course was told.
• Treat work as help with living costs, not as tuition funding. A budget that depends on term-time earnings is fragile, and universities do not accept it as evidence of funds.
• Breaching work conditions is a serious matter with consequences for your visa and any future application.

After your course finishes

Whether you can remain in the UK afterwards, and for how long, is a separate question from the student visa itself — staying in the UK after your studies covers the routes and what they do and do not lead to.

The Graduate route allows eligible students who have completed a UK degree to stay and work for a defined period after graduating. It is a separate application made from inside the UK, and eligibility depends on completing the course you were sponsored for.

For many students this is a material part of why the UK is worth the cost — but it is a distinct route with its own rules, and it is worth understanding before you arrive rather than in your final term. Our guide to the UK Graduate Route visa covers eligibility and the common misconceptions.

Bringing family

Whether dependants can come with you depends on your course level and length. The rules here changed in recent years and are more restrictive than many older guides suggest. If this affects your decision, confirm the current position on GOV.UK: Student visa — family members before committing to a course rather than relying on any secondhand summary. Our guide to bringing dependants to the UK sets out how the rule is structured by course type.

Where StudyUKToday Fits In

We don’t submit visa applications, handle immigration paperwork, or advise on individual visa cases. That’s a regulated area, and it’s genuinely better handled through official channels. What we do is the part before that:

• Helping you choose the right course and university.
• Reviewing your documents so they’re in good order before your university relies on them.
• Making sure you understand your CAS once it’s issued, since that’s the document your visa application will be built around.

Getting the university stage right is what makes the visa stage straightforward. Most visa problems are created months earlier, by a document nobody checked.

Where to Apply

Student visa applications are made through the UK government’s own official website (gov.uk). This is the accurate, authoritative source for current requirements, fees, and processing times. Always start there rather than a third-party summary, including this one.

Frequently Asked Questions

What are the main requirements for a UK student visa?

In general terms: a valid CAS from a licensed sponsor, evidence you can cover fees and living costs, English language evidence in an accepted form, and a valid passport. Additional requirements can apply depending on your nationality and circumstances. gov.uk lists the current position.

Can I apply for my visa before I have a CAS?

No. The CAS is what the application is built around, which is why any delay in meeting your offer conditions delays the visa too.

How much money do I need to show?

It depends on your course fees and whether you will study in London or elsewhere, and the figures are reviewed periodically. We deliberately don’t publish amounts here — check gov.uk for the current requirement.

How long does a UK student visa take?

Processing times vary by country and by season, and they lengthen around peak intakes. Treat any figure you read as an estimate rather than a guarantee, and build slack into your plan. Our guide to how long a UK student visa takes covers what actually drives it.

Can I work on a UK student visa?

Limited paid work is permitted during term time, with more during vacations. The exact limit depends on your course level and is stated on your visa. Some work types are excluded entirely.

What happens if my visa is refused?

Refusals usually come with reasons. Depending on those reasons a fresh application may be possible, sometimes quickly. This is a regulated area and worth taking proper advice on rather than immediately reapplying.

Do I need IELTS for a UK student visa?

Not necessarily. The requirement is that your English is evidenced in a form accepted for your course, which may be a test, a waiver, or a Medium of Instruction letter. Some courses specifically require a UKVI-approved test. Our guide on applying without IELTS covers how this works.

Do you handle the visa application for me?

No, and we would be cautious of anyone who says they will. Visa administration is regulated and best done through official channels. What we do is make sure the university stage — offer, documents, CAS — is right, because that is where most visa problems actually begin.
