UK Student Visa: Requirements, Documents, Refusals and Legal Advice
The UK Student visa is the main immigration route for international students aged 16 or over who want to study an eligible course with a licensed student sponsor in the UK. It replaced the old Tier 4 (General) route, although many people still use the old terminology when searching for advice.
A Student visa application can look straightforward when the applicant has a university offer and a Confirmation of Acceptance for Studies. In practice, refusals and delays often arise from avoidable problems: incorrect financial evidence, CAS inconsistencies, unclear academic progression, doubts about whether the applicant is a genuine student, previous immigration history, missing consent documents for younger applicants, or misunderstanding work and dependant rules.
This guide explains the main requirements, the documents usually needed, the common risk areas, and when a paid consultation with a UK immigration lawyer may be useful before submitting the application.
UK Student visa requirements
Who can apply for a Student visa?
You can apply for a Student visa if you are 16 or over and you want to study on a further or higher education course in the UK. If you are under 18 and you want to study at an independent school, the Child Student route may be more appropriate.
In broad terms, a Student visa application usually requires you to show that:
- you have a Confirmation of Acceptance for Studies, usually called a CAS, from a licensed student sponsor;
- your course is eligible under the Student route;
- you meet the financial requirement, unless an exemption applies;
- you meet the English language requirement, where required;
- you are a genuine student;
- you meet the suitability requirements and do not fall for refusal under the relevant Immigration Rules;
- you provide any additional documents required for your age, course, nationality or personal circumstances.
The CAS is central to the application
A CAS is an electronic record issued by a licensed student sponsor after you have been accepted for a course. It is not simply an offer letter. It contains information that the Home Office uses to assess the application, including the sponsor, course, start and end dates, fees and other details.
Before submitting the application, it is important to check that the CAS details match the application form and your supporting documents. Problems can arise where there are differences in names, course dates, course level, fees paid, previous study history, academic progression or the explanation for a change of course.
If you have more than one CAS, you must use the CAS for the institution where you actually intend to study. Once a CAS is used, other associated CAS records may become obsolete. Applicants should not treat CAS selection as an administrative detail.
Financial requirement: tuition fees and living costs
Most Student visa applicants must show that they have enough money for course fees and living costs. The required living-cost amount depends on whether the course is in London or outside London. The Home Office currently states that applicants need either £1,529 per month for courses in London or £1,171 per month for courses outside London, for up to 9 months. The amount for tuition fees depends on the CAS and any payments already made to the sponsor.
The financial requirement is one of the most common areas for avoidable mistakes. Applicants should check:
- whether they need to show funds at all, including whether the 12-month lawful residence exemption applies;
- whether the correct living-cost figure has been used;
- whether course fees already paid are correctly reflected on the CAS;
- whether bank statements cover the required period and meet the Home Office format rules;
- whether funds are in an acceptable account and held by an acceptable person;
- whether currency conversion, closing balance dates and document dates create any problem;
- whether official financial sponsorship evidence is needed.
A student who submits weak or incorrect financial evidence may be refused even if they genuinely have enough money. It is safer to check the evidence before applying than to try to repair the position after a refusal.
English language requirement
Depending on the course and sponsor, the applicant may need to show English language ability. In some cases, the sponsor assesses English as part of the CAS process. In other cases, a Secure English Language Test or other acceptable evidence may be required.
Applicants should not assume that any English certificate will be accepted. The correct evidence depends on the course level, sponsor type, previous qualifications and Home Office rules in force at the date of application.
Genuine student requirement
The applicant must be a genuine student. This is not just a question of having a CAS. The Home Office may look at the full context, including the applicant’s immigration history, education history, reasons for choosing the course, post-study plans, financial circumstances, dependants, previous refusals, gaps in study and whether the course makes sense in light of the applicant’s background.
A credibility interview may be used in some cases. A weak interview, vague answers, inconsistent information or an unconvincing explanation of the course choice can create refusal risk. Applicants with unusual study plans, previous refusals, a long gap in education, a lower-level course after higher study, repeated course changes or complex financial arrangements should consider obtaining advice before applying.
Academic progression and previous UK study
If you already have or previously had Student permission, Tier 4 permission or pre-Tier 4 student permission, your CAS may need to confirm academic progression. This can matter where you are changing course, repeating study, moving to a lower level, taking a second course at the same level, or returning to study after time in another immigration route.
Academic progression is often misunderstood. A course can be academically valuable but still create immigration questions if the CAS and application do not explain why it satisfies the route requirements. Applicants should address this before the application is filed, not after a Home Office concern is raised.
ATAS, TB testing and additional documents
Some students need an Academic Technology Approval Scheme certificate before applying, particularly for certain sensitive subjects at postgraduate level. Some applicants also need a tuberculosis test certificate, depending on nationality, residence history and the country from which they apply.
Applicants under 18 need additional evidence, including parental or legal guardian consent for the application, living and care arrangements in the UK, and travel to the UK. They may also need evidence of their relationship to their parent or guardian.
Practical issues before and after applying
When to apply and how long a decision usually takes
The timing of the application matters. The Home Office currently states that decisions usually take 3 weeks for applications made outside the UK and 8 weeks for applications made inside the UK. Faster decision services may be available in some cases, but they are not guaranteed to be available and do not fix weak evidence.
You can usually arrive in the UK before the course starts, but the permitted arrival period depends on course length. You must not travel before the start date shown on your visa or digital immigration status.
Student visa length and future routes
The length of permission depends on the course, course level and previous study. GOV.UK currently states that if you are 18 or over and studying at degree level, you can usually stay for up to 5 years, while below degree level the usual limit is up to 2 years.
Some students may later extend their Student visa, switch into another route from inside the UK, or apply under the Graduate route after successfully completing an eligible UK course. The Graduate route rules are changing: GOV.UK currently states that a Graduate visa allows 2 years if applied for on or before 31 December 2026, 18 months if applied for on or after 1 January 2027, and 3 years for a PhD or other doctoral qualification.
Students who are planning a long-term UK immigration strategy should not look at the Student visa in isolation. Course choice, sponsor compliance, work conditions, completion dates and future switching options can all affect later plans.
Can dependants come with a Student visa holder?
Student dependant rules are now significantly narrower than they used to be. Partners and children may be able to apply as dependants only if the Student meets the relevant requirements. GOV.UK currently states that the Student must be either a government-sponsored student starting a course lasting longer than 6 months, or a full-time student on a postgraduate level course lasting 9 months or longer. For postgraduate courses starting on or after 1 January 2024, further restrictions apply and the course must fall within the permitted categories.
This is a high-risk area for families. A student may be eligible for the main visa but still be unable to bring a partner or child. Families should check dependant eligibility, finances and timing before committing to tuition deposits, travel arrangements or accommodation.
Work conditions on a Student visa
A Student visa normally allows study and may allow work, but the exact conditions depend on the course, sponsor and the permission granted. Many students can work during term time within a weekly limit and can work more during vacations, but some have more restricted conditions or no right to work.
Students must check their own eVisa or grant conditions. Breaching work conditions can cause serious immigration consequences, including future refusal risk. Students should be especially careful about self-employment, business activity, professional sport, and work that does not fit the conditions attached to their permission.
Visa brake restrictions for certain nationalities
Current Home Office guidance includes visa brake restrictions affecting Student visa applications by nationals of Afghanistan, Cameroon, Myanmar and Sudan from 26 March 2026. Applicants affected by nationality-specific restrictions should take advice before making assumptions based on older university, agent or online guidance.
Common Student visa refusal risks
Student visa refusals are often avoidable. Common risk areas include:
- financial documents that do not meet the strict evidential rules;
- using the wrong financial amount for London or outside London;
- relying on funds held by someone who is not an acceptable financial sponsor or parent/legal guardian;
- CAS information that does not match the application;
- unclear academic progression or unexplained course changes;
- weak answers in a credibility interview;
- failure to provide ATAS, TB or parental consent documents where required;
- previous overstaying, deception concerns or adverse immigration history;
- misunderstanding dependant eligibility;
- applying from inside the UK when switching is not permitted from the current route.
What if a Student visa is refused?
A Student visa refusal does not always mean that study in the UK is impossible, but it must be handled carefully. The correct next step depends on the reason for refusal, the deadline, whether administrative review is available, whether the refusal contains a factual error, whether fresh evidence is needed, whether the CAS remains valid, and whether a new application is strategically safer.
Do not simply reapply with the same evidence unless the refusal reason has been properly understood. A repeated refusal can make the case harder, especially where the Home Office has raised credibility, deception or suitability concerns.
When legal advice may be useful
Many straightforward Student visa applications are prepared directly by students with support from their education provider. Legal advice becomes more important where the case has risk, complexity or serious consequences if refused.
A paid consultation may be useful if:
- you have had a previous UK visa refusal;
- your financial evidence is not simple;
- you have had a long gap in education or an unusual academic pathway;
- you are applying for a lower-level course after higher study;
- you previously studied in the UK and academic progression is an issue;
- you want to bring dependants;
- you are switching from another UK immigration route;
- you have overstaying, breach of conditions, deception or suitability concerns;
- your CAS, course dates, fees or documents do not appear consistent;
- you have received a refusal and need to understand whether to challenge or reapply.
Legal advice cannot make an ineligible applicant eligible and cannot guarantee a successful visa decision. It can, however, help identify risks, check whether the evidence meets the rules, reduce avoidable mistakes and clarify the strongest available route before money, time and study plans are put at risk.
How UK Immigration Law can help
UK Immigration Law can advise on Student visa applications, extensions, switching issues, dependant applications, refusal strategy and complex student-route problems. We can review your circumstances, identify the relevant requirements, check risk areas and advise on the documents and explanation likely to be needed for your case.
If your case involves previous refusals, complicated finances, dependants, unusual study history or a time-sensitive course start date, early advice is usually better than waiting until after a refusal.

Frequently asked questions
Can I apply for a UK Student visa after already completing a degree or master’s degree?
Possibly, but the application may need a careful explanation. The Home Office may look at academic progression, your study history, why the new course is appropriate and whether you are a genuine student. This can be particularly important if you are applying for a lower-level course after higher study, changing field significantly or returning to study after a long gap.
Can my partner and children come with me on a Student visa?
Not always. Student dependant rules are restricted and depend on the type, level and length of your course, whether you are government-sponsored, and when the course starts. Many undergraduate and taught postgraduate students cannot bring dependants. Check eligibility before paying deposits or making family travel plans.
Should I challenge a Student visa refusal or make a new application?
It depends on the refusal reason, available remedy, deadline, CAS position and whether the problem can be fixed with better evidence. Some refusals may be suitable for administrative review if the Home Office made an error. In other cases, a properly prepared new application may be more appropriate. The refusal letter should be reviewed before deciding.
