UK Student Visa Brake in 2026: What Cameroon and Sudan Applicants Need to Know

Official GOV.UK guidance on the 2026 UK Student visa brake, whether a CAS helps, and what Cameroon and Sudan applicants should check next.

Source check completed: 20 July 2026

If you are a national of Cameroon or Sudan applying from outside the UK for a UK Student visa, an online application submitted after 12:01am on 26 March 2026 will be refused under the current visa brake. This is true even if you already have a valid Confirmation of Acceptance for Studies (CAS).

The current GOV.UK guidance says the Student-route visa brake applies to nationals of Afghanistan, Cameroon, Myanmar and Sudan who are making out-of-country Student visa applications. For many UniDoxia readers, the practical question is simple: does a CAS still help if you are applying from Cameroon or Sudan? Right now, the official answer is no for new out-of-country Student visa applications covered by the brake.

What the current rule means

The GOV.UK visa-brake guidance says affected Student visa applications made outside the UK are refused based on the main applicant's nationality. It does not depend on where you live or where you submit the application from.

For Student visa applicants, the affected nationalities are:

• Afghanistan
• Cameroon
• Myanmar
• Sudan

For a Cameroon or Sudan applicant, that means the normal Student-route planning sequence — offer, CAS, funds, visa application, travel — breaks down at the visa stage if the application falls within the current visa-brake rule.

Does a valid CAS override the visa brake?

No. The official GOV.UK visa-brake guidance says applications submitted after the rule took effect are refused even if the applicant already has a valid CAS.

That point matters because many students assume a CAS automatically protects their case. It does not. A CAS remains an important sponsorship document in the normal Student route, but it does not cancel or bypass the current visa-brake restriction.

If you still need to understand the normal evidence side of the Student route for future planning, see our guide to UK Student visa funds in 2026 and the evidence mistakes to avoid.

What sponsors have been told about CAS

The official student-sponsor guidance goes further. It says sponsors should not issue a CAS to affected nationals while the visa brake is in place, and they may wish to withdraw a CAS already issued where the student had not applied before 26 March 2026.

So if you are a Cameroon or Sudan applicant and a university previously issued a CAS, do not assume it will stay active indefinitely. Check the current position directly with the sponsoring institution before paying more fees or making travel plans.

What if you already have a valid UK visa?

The current GOV.UK guidance says the visa brake does not cancel a visa that has already been granted. If you already hold a valid UK visa:

• your permission remains valid until its expiry date
• you must continue to follow your visa conditions
• you may still be able to make an in-country application if you are eligible

That distinction is important. The brake is aimed at out-of-country Student entry clearance applications, not every situation involving a student from an affected country.

What if you are a dual national?

The Home Office caseworker guidance says the visa brake affects out-of-country applications where the main applicant has made their application using a passport or travel document which confirms that they are a national of one of the affected countries. The same guidance says applications by dual nationals using a different nationality should be considered in line with that nationality.

This is a technical area, so do not guess. Check the official guidance carefully and make sure any application strategy matches your actual passport, nationality position and eligibility.

A practical checklist before you spend more money

Before paying another deposit, courier fee or travel cost, check these points:

1. Confirm whether your planned application is outside the UK or inside the UK.
2. Confirm which nationality and passport would be used for the application.
3. Do not assume an old or existing CAS solves the problem.
4. Ask the university or sponsor whether the CAS is still valid and whether they are still prepared to support the case.
5. Recheck the latest GOV.UK visa-brake and Student-route pages on the day you act.
