Deferring course after student visa granted

Short answer

Yes, you can defer your course after your Student visa has been granted, but doing so almost always means your current Student visa will be cancelled and you will need to apply again with a fresh Confirmation of Acceptance for Studies (CAS). A Student visa is tied to a specific CAS for a specific course starting on a specific date at a named sponsor. If the course you were sponsored for no longer starts when your visa was issued for, the basis of that visa falls away.

Why deferral affects the visa

Your Student visa is granted on the basis of the particular CAS your sponsor assigned to you. That CAS records the course, the sponsor, and the start and end dates. When you defer, the original CAS is effectively withdrawn or superseded, because you are no longer starting that course on the date the visa covers.

Your sponsor (the university or college) has a duty under its sponsor licence to keep the Home Office informed about changes to a sponsored student’s circumstances. If you defer, the institution will normally report this to UKVI, and the practical consequence is that the visa granted on the original CAS is curtailed or cancelled. You will then not be able to use it to travel to or enter the UK for the deferred course.

The two common situations

The outcome depends on whether you have already used the CAS to apply for the visa.

If you have not yet used your CAS to apply for a visa, the position is simpler. The CAS is withdrawn and the sponsor issues a new CAS for the deferred start date, and you apply for your visa using that new CAS. There is no wasted application.

If you have already applied for and been granted the visa, the visa granted on that CAS will normally be cancelled, and you will need to request a new CAS from your sponsor and make a fresh visa application based on the deferred course start date. In practice you would apply for the new visa within around three months of the new course start date, in line with the usual window for Student applications made from outside the UK.

Cost consequences

This is the main practical downside. If your visa has already been granted and you then defer, you will generally have to pay again. You are usually not entitled to a refund of the visa application fee, and the Immigration Health Surcharge you paid for the cancelled visa is not normally refunded either where the visa was actually granted. You would then pay the fee and surcharge again for the new application. Refund entitlement for the surcharge depends on whether the original visa was granted and used; if a visa is granted, refunds are limited, so check the current refund rules on GOV.UK before assuming you will get money back.

Practical steps

1. Tell your sponsor’s international student or immigration team and your academic department as early as possible. They control the CAS and the reporting to the Home Office, so nothing should be done without coordinating with them.

2. Ask the institution to confirm in writing exactly what will happen to your current visa, when they will report the deferral, and when they can issue a new CAS for the deferred start date.

3. Do not travel to the UK on the original visa once you have decided to defer, because it is being cancelled and entering on it would be inappropriate.

4. Budget for a second visa fee and a second Immigration Health Surcharge payment, and check the current GOV.UK refund position for any amounts you may be able to reclaim.

5. Make the new application in good time before the deferred start date, using the new CAS, and check that your maintenance funds, English language evidence and other documents still meet the requirements at the time you reapply.

Points to watch

Rules and financial requirements can change between your original application and the deferred one, so you must meet the requirements in force at the time of the new application, not the earlier ones.

If you are deferring for a short period only, ask your institution whether the change can be handled without cancelling the visa; but in most cases a genuine change of course start date to a later academic year will require a new CAS and a new visa.

The precise handling of the CAS and reporting can vary slightly between institutions, and each sponsor has its own internal deferral policy and deadlines, so the answer that matters most in practice is what your specific sponsor’s immigration team tells you.

Key missing facts

The best guidance depends on whether you have already used the CAS to apply, whether the visa has actually been granted, how long the deferral is, and whether you are currently inside or outside the UK. If you tell me those details I can be more specific about the likely process and cost in your situation.
