The UK Student Visa Is Not Complicated. It's Just Poorly Explained.
Every year, thousands of international students get their UK visa applications delayed or refused — not because they're ineligible, but because they missed a step, submitted the wrong document, or misunderstood the financial requirements.
This guide covers everything you need to know about the UK Student Visa (formerly Tier 4) in 2026, in plain language, with exact figures and timelines.

Visa Types: Which One Do You Need?
| Visa | Who It's For | Duration | |---|---|---| | Student Visa | Courses longer than 6 months (degree-level or above) | Length of course + extra time | | Short-term Study Visa | Courses up to 6 months (e.g., English language) | 6 or 11 months | | Child Student Visa | Students aged 4–17 at independent schools | Length of course | | Graduate Visa | Post-study work (after completing a qualifying degree) | 2 years (3 for PhD) |
This guide focuses on the Student Visa — the one most international students need for undergraduate, Master's, or PhD programmes.

The 8-Step Application Process
Step 1: Get Your University Offer
Before you can apply for a visa, you need an unconditional offer from a UK university that holds a Student Sponsor Licence.
How to check: Search the Register of Licensed Sponsors on GOV.UK. If your university isn't listed, you cannot get a Student Visa through them.
---
Step 2: Receive Your CAS (Confirmation of Acceptance for Studies)
Your university issues a CAS number — a unique electronic reference that confirms your place. This is not a physical document; it's a reference number you enter on your visa application.
Key CAS details:
| Detail | What to Know | |---|---| | What it contains | Your personal details, course info, fees paid, and conditions | | When you get it | Usually 3–6 months before your course starts | | Validity | 6 months from issue date | | Can you have multiple? | Only one active CAS at a time |
Critical check: Verify every detail on your CAS is correct — name spelling, passport number, course dates. Errors here cause visa refusals.
---
Step 3: Prove Your Financial Standing
This is where most applications go wrong. You must prove you can pay for:
1. Remaining tuition fees (amount on your CAS minus any deposits paid) 2. Living costs for up to 9 months
2026 Living Cost Requirements
| Location | Monthly Requirement | 9-Month Total | |---|---|---| | London (inner and outer) | £1,529/month | £13,761 | | Outside London | £1,171/month | £10,539 |
Total funds needed = Remaining tuition + Living costs
Accepted Evidence
| Source | Requirements | |---|---| | Personal bank account | Funds held for 28 consecutive days ending no more than 31 days before application | | Parent/legal guardian account | Same 28-day rule + birth certificate + letter of consent | | Official financial sponsorship | Letter from sponsor (government, international organisation, university) | | Student loan | Official loan letter showing amount and that it's for studying in the UK |
Common Financial Mistakes
- Funds dipping below the required amount during the 28-day period — even for one day
- Using a fixed deposit that can't show 28-day statements
- Bank statements in a foreign language without certified translation
- Joint accounts where the applicant is not the primary holder (varies by country)
- Submitting statements that are older than 31 days at the time of application

Step 4: Gather Your Documents
Here's the complete document checklist:

Step 5: Apply Online
Apply on the GOV.UK website.
When to apply:
| Situation | Earliest Application Date | |---|---| | Applying from outside the UK | Up to 6 months before your course starts | | Applying from inside the UK (switching visa) | Up to 3 months before your course starts |
Application fee (2026):
| Location | Fee | |---|---| | Applying from outside the UK | £524 | | Applying from inside the UK (switching/extending) | £524 |
Immigration Health Surcharge (IHS):
| Duration | Annual Cost | |---|---| | Full-time students | £776/year (prorated for courses under 1 year) |
Example total cost for a 1-year Master's:
- Visa fee: £524

(Plus biometrics appointment fee, which varies by country)

Step 6: Biometrics Appointment
After submitting your online application, you'll book an appointment at a Visa Application Centre (VAC) to provide:
- Fingerprints
- Photograph
- Document submission (originals or scanned via the UKVI app)
Processing times:
| Service | Timeline | Additional Cost | |---|---|---| | Standard | 3 weeks (15 working days) | Included | | Priority | 5 working days | ~£500 (varies by country) | | Super Priority | 1 working day (where available) | ~£1,000 (varies by country) |
Pro tip: Apply early. Standard processing during peak season (June–August) can stretch to 4–6 weeks.

Step 7: Receive Your Decision
You'll receive one of three outcomes:
| Decision | What Happens | |---|---| | Granted | You get an eVisa — an online record of your immigration status | | Refused | You receive a refusal letter explaining why | | Administrative Review | Rare; used if you believe a caseworker error was made |
Get access to your eVisa by setting up a UKVI account. You'll need to link your travel document to your UKVI account. This should be the travel document you use to come to the UK.
---
Step 8: Arrive and Register
Once in the UK:
1. Register with your university's international student office 2. Register with a GP (doctor) using your university letter 3. Open a UK bank account (most require a university letter) 4. Register with the police (only required for nationals of certain countries)

Working While Studying
| Situation | Hours Allowed | |---|---| | During term time (degree-level) | Up to 20 hours/week | | During holidays | Full-time | | Placement as part of course | Full-time (if it's an assessed part of your programme) | | Foundation/pre-sessional courses | 10 hours/week during term |
What counts as "term time" is defined by your university, not the calendar. Check your academic schedule.
Prohibited work:
- Self-employment or freelancing
- Professional sportsperson or entertainer
- Permanent full-time work

After Graduation: The Graduate Route
When you complete your degree, you can switch to the Graduate Visa:
| Detail | Info | |---|---| | Duration | 2 years (Bachelor's/Master's) or 3 years (PhD) | | Work restrictions | None — any job, any level, any sector | | Cost | £880 + IHS (£1,035/year) | | Can you switch to Skilled Worker? | Yes, if you find a qualifying job |
This is one of the most generous post-study work visas in the world. You don't need a job offer to apply — just a completed qualifying degree.

Frequently Asked Questions
Can I bring my family? If your postgraduate level course starts on or after 1 January 2024, it must be either a PhD or other doctorate (RQF level 8), or a research-based higher degree. Your dependants will need separate visa applications and must meet financial requirements.
Can I switch from a visitor visa to a student visa? No. You must leave the UK and apply from your home country (with very limited exceptions).
What if my visa is refused? You can reapply immediately with corrected documentation. There's no mandatory waiting period, but address every reason in the refusal letter.
Do I need to show funds if I have a full scholarship? If your scholarship covers tuition and living costs and this is stated on your CAS, you may not need additional financial evidence. Check your CAS carefully.
Can I travel during my studies? Yes. Your visa allows multiple entries. Just ensure your BRP/eVisa is valid for re-entry.

The Bottom Line
The UK Student Visa process is methodical, not mysterious. The students who get refused are almost always the ones who rush the financial evidence, miss a document, or don't read the requirements properly.
Give yourself at least 3 months between receiving your CAS and your course start date. Follow the checklist. Don't cut corners on the 28-day financial requirement.
And remember: once you're here, the Graduate Route gives you 2–3 years of unrestricted work. The visa process is the hard part. What comes after is the opportunity.
