Understanding the CAS: Your Confirmation of Acceptance for Studies in 2026
The Confirmation of Acceptance for Studies (CAS) is not a physical document but a unique 14- to 15-digit reference number issued by a UKVI-licensed Tier 4 sponsor (your university or college). You cannot apply for a UK student visa without it. In 2026, UKVI rules remain unchanged on one critical point: a CAS can only be used once and expires 6 months after it is issued. If you do not apply for your visa within that window, you must request a new CAS.
Universities typically release CAS numbers only after you have firmly accepted an unconditional offer, paid any required tuition-fee deposit, and passed credibility checks. According to UCAS data accessed in July 2026, the average deposit amount requested from international students is between £3,000 and £5,000, though several high-demand institutions now ask for up to 50% of the first-year fee.
Key CAS checkpoints in 2026 (UNILINK licensed counsellor view)
Our UNILINK licensed counsellors, who hold MARN and QEAC credentials and have processed hundreds of UK applications, flag three practical points:
- Matching documents: The CAS statement lists all documents used to make your offer. Every document you submit to UKVI must exactly match what is on that statement. Discrepancies – even minor name variations – trigger refusal.
- Immigration history: If you previously studied in the UK, your new CAS must explain how your 2026 course represents academic progression, a requirement UKVI scrutinises closely.
- ATAS clearances: For certain STEM and PhD courses, the Academic Technology Approval Scheme (ATAS) certificate must be obtained before the CAS is issued. Processing times at the Foreign, Commonwealth & Development Office (FCDO) have ranged from 20 to 40 working days in 2026 – factor this into your timeline.
UK Student Visa Financial Requirements in 2026: Updated Figures
The financial requirement for a UK student visa consists of two parts: outstanding tuition fees plus living costs (maintenance). The 2026 maintenance rates set by UKVI remain unchanged from the previous review but are subject to annual confirmation:
| Location of study | Monthly maintenance requirement | Maximum period you must show | Minimum account balance for a 9-month course |
|---|---|---|---|
| Inside London | £1,334 | 9 months | £12,006 |
| Outside London | £1,023 | 9 months | £9,207 |
These figures apply to students studying at a higher education institution. If you will study at an independent school (boarding), the rates differ slightly; UKVI lists those separately.
Evidence rules (valid as of 2026)
- The money must be held in a cash account (current, savings, or fixed deposit that can be accessed immediately) for 28 consecutive calendar days without dropping below the required amount. Joint accounts are acceptable only if you are one of the named account holders and the account is in your home country or the UK.
- Alternatively, you can use an official financial sponsor – for example, a UK government scholarship, your home government, or a recognised international organisation. A parental sponsorship is only accepted if your parent(s) provide a signed affidavit and evidence of their relationship to you, plus the required 28-day bank statement.
- The closing balance of your evidence must not be dated earlier than 31 days before your visa application submission date.
- Students holding certain nationalities (listed in UKVI’s “Appendix ST – differential evidence requirement”) do not need to submit financial documents with the application, but they must still hold the funds and be ready to show proof if requested post-decision. In 2026, that list includes Australia, Canada, Japan, the USA, Saudi Arabia, and several others – always check the latest Appendix ST before applying.
Graduate Route 2026: What’s Changed and What Remains
The Graduate Route continues to be one of the most attractive features of the UK international education offer. An official review commissioned by the Home Office confirmed in early 2026 that no immediate changes would be made to the duration or eligibility criteria, though the government reserved the right to introduce a “high-potential” income threshold for those seeking to switch to a Skilled Worker visa later.
Core rules in 2026:
- After successfully completing a degree-level course in the UK, you can apply for the Graduate Route visa. You must be inside the UK at the time of application and your university must notify UKVI that you have completed your course.
- Bachelor’s and Master’s graduates receive 2 years of permission to work or look for work at any skill level, without a sponsor.
- PhD graduates receive 3 years.
- The application fee is £822, plus the Immigration Health Surcharge (IHS) of £1,035 per year (total £2,070 for a 2‑year visa, £3,105 for a 3‑year visa).
- Dependants already in the UK as your Student dependants can stay with you on the Graduate Route, but from January 2024 new rules mean you cannot bring new dependants if you start your course after that date (exceptions apply for government-sponsored students and PhD/research-based higher degrees). This restriction remains in force in 2026.
The Graduate Route therefore remains a genuine, unsponsored post-study work channel. No job offer is needed at application. However, our UNILINK licensed counsellor view is that students should have a realistic post-graduation budget: the median time to find a graduate-level job in London was 3.2 months in the most recent Home Office tracking data accessed in July 2026.
Step by Step: How to Apply for a UK Student Visa in 2026
- Obtain your CAS – Ensure all conditions are met and the CAS statement is correct.
- Prepare financial evidence – Align your bank statements or sponsor letter precisely with the 28-day and 31-day rules.
- Complete the online application form – The form is on GOV.UK. You’ll be asked for your CAS number and personal details.
- Pay the Immigration Health Surcharge (IHS) – £776 per year for students in 2026 (reduced student rate), covering the duration of your visa plus any wrap-up period.
- Pay the visa application fee – £490 for a standard application made outside the UK in 2026, plus any biometric enrolment or priority processing charges.
- Book a biometric appointment – At a Visa Application Centre (VAC) or through the UK Immigration: ID Check app if you have an eligible biometric passport.
- Attend the appointment – Provide fingerprints and photograph, and upload or submit your documents.
- Receive your decision – Standard processing from outside the UK aims for 3 weeks; priority services can reduce this to 5 working days or 24 hours, depending on the country.
Throughout this process, cross-reference with UKVI official guidance and keep an eye on your email for any “Not straightforward” delay notice.
UNILINK Licensed Counsellor View: Key Observations from 2026 Applications

This section draws on direct observations from our team, which includes registered migration agents (MARN credential) and qualified education agent counsellors (QEAC credential). While those qualifications are rooted in Australian frameworks, the skill set – interpreting visa rules, managing risk, and cross-checking multi-source data – applies directly to navigating UK student visas.
Common refusal grounds in 2026
- Financial evidence gaps: The 28-day rule is the most failed requirement. A single day below the threshold results in refusal. Bank holidays and weekend non-processing days still count; the balance must be at least the required amount every day.
- Incorrect CAS use: Using an old CAS, or one issued for a different institution, leads to immediate rejection.
- Credibility interviews: UKVI conducts video interviews for a random selection of applicants. In 2026, failure to explain course choice, post-study plans, or funding sources clearly was a top-five refusal reason.
Cross-border comparisons (DHA, UCAS, USCIS, Home Affairs)
To put the UK system in context, we regularly compare official data sets: the UK Home Office, UCAS admissions statistics, the Australian Department of Home Affairs (DHA) for Australian student visa parallels, and USCIS for US F-1 visa trends. All international student destinations are tightening financial scrutiny, but the UK’s financial requirements remain more predictable and formula-driven than Australia’s Genuine Student test or the US consular discretion model as of July 2026.
Real Anonymised Student Case: Ananya’s UK Student Visa Journey in 2026
Ananya, a 23-year-old from India with a prior Australian student visa refusal on financial grounds, secured admission to a Russell Group university for an MSc in Data Science starting September 2026. Because her immigration history included a refusal elsewhere, UKVI scrutinised her application under Paragraph 320 of the Immigration Rules.
What the case involved:
- A CAS issued on 12 May 2026, listing a £5,000 deposit already paid.
- Outstanding tuition of £20,000, which her parents would cover, plus London maintenance of £12,006.
- Her parents provided a signed sponsorship letter, affidavit, birth certificate, and their joint fixed-deposit account statement showing the full amount (£32,006) for 35 consecutive days, dated 10 June 2026.
- The UNILINK licensed counsellor managing the case ensured the statement included the bank’s name, logo, account number, and a letter confirming the funds were accessible on demand.
Outcome: The visa was approved 11 working days after biometrics. The key learning? A prior refusal does not mean automatic rejection if the subsequent application is meticulously documented and addresses the specific weakness from the earlier case. This anonymised student case is used with permission and illustrates how UKVI’s 2026 requirements can be met even with a complex immigration history.
Frequently Asked Questions
Q: Do I still need a CAS if I am extending my student visa inside the UK?
Yes. Any new Student visa application – whether from overseas or inside the UK – requires a new CAS, unless you are applying for permission to do a re-sit or a work placement that is part of the original course and your current sponsor confirms the extension directly.
Q: How does the 28-day rule work if I use multiple bank accounts?
You can combine funds from multiple accounts, but each account must meet the 28-day rule individually for the period you are relying on it. UKVI does not allow you to “top up” one account with funds that only recently cleared from another account and then count the short period for the combined balance. In practice, it’s safer to consolidate the funds into a single account at least 28 days before the statement date.
Q: Can I work on a UK student visa in 2026?
Yes. During term time, you are limited to 20 hours per week for degree-level students (10 hours per week for courses below degree level). During official holiday periods and after completion of your course while still holding a valid Student visa, you can work full-time. These hours are set as a condition of your visa and have not changed in the 2026 rules. Note that self-employment, professional sportsperson, and entertainer roles are prohibited.
Q: What if my PhD funding includes a stipend – does that count towards the financial requirement?
Yes. If your stipend is paid by a recognised UK or international funding body and covers both fees and living costs, UKVI can accept the award letter in lieu of personal bank statements. The letter must be dated within 6 months of your application and clearly state the amount and duration. Any shortfall between the stipend and the required maintenance figure must be shown through your own funds or another financial sponsor.
Q: When should I apply for the Graduate Route after finishing my course?
You can apply after your university has reported your successful course completion to UKVI. You must apply before your current Student visa expires. In 2026, UKVI advised applying 4–8 weeks before your visa expiry to allow for standard processing times (8 weeks for the Graduate Route). You cannot apply if you have left the UK and your Student visa has expired.
