University CAS delay or refusal

What a CAS is and why delays or refusals happen

A Confirmation of Acceptance for Studies (CAS) is the electronic reference a licensed student sponsor (the university) issues so that you can apply for a Student visa. The university is not just doing you a favour: it holds a Home Office sponsor licence, and issuing a CAS is a formal act that carries obligations and risk for the institution. That context matters, because most delays and refusals are not arbitrary or unlawful. They usually reflect the university checking that it can lawfully sponsor you and that you are likely to meet the immigration requirements. Common reasons include an unpaid or incomplete deposit, outstanding conditions on your offer, missing or unverified academic documents, English language evidence not yet supplied, a genuine student or credibility assessment, a previous visa refusal, or questions about your finances or immigration history.

Before treating a delay as a breach or a refusal as wrongful, it is worth identifying which of these ordinary explanations applies, because the right response is very different depending on the cause.

Legal position

Your relationship with the university is primarily contractual, governed by the offer letter and the university’s admissions terms and consumer protection law, alongside the university’s own published policies. There is generally no free-standing legal right to be issued a CAS. A university can lawfully decline to issue one, or delay it, where its conditions have not been met or where it has genuine concerns about its sponsor duties.

However, the university must act consistently with its own published admissions and CAS policies, must not mislead you, and must treat you fairly. If it has confirmed you meet all conditions and then unreasonably refuses or sits on the CAS, or if it applies criteria it never disclosed, you may have grounds for complaint on the basis that it has not followed its own process or has acted unfairly. Consumer protection principles (drawn from the Consumer Rights Act 2015 and Competition and Markets Authority guidance on higher education) require the information the university gives applicants to be clear, accurate and not misleading, and require its terms and processes to be fair.

Importantly, the CAS decision is separate from the visa decision. The university issues the CAS; UK Visas and Immigration (UKVI) then decides the visa. A refusal by the university is not something you can appeal to the Home Office, and a visa refusal is a separate matter with its own remedies.

First step: find out the exact reason

Everything turns on why the CAS has not been issued, so pin this down in writing.

1. Ask the admissions or international office, in writing, to confirm precisely what is outstanding and what you must do to obtain the CAS.

2. Check your own position: is your deposit paid, are all academic and English language documents submitted and verified, have you met every condition on the offer, and have you completed any pre-CAS or credibility interview the university requires.

3. Ask for a realistic timescale. Many universities publish a service standard, often around ten working days from when all conditions are met.

If the delay is because something is outstanding on your side, supplying it promptly is usually the fastest route to resolution.

If the delay is unreasonable

If you have genuinely met all published conditions and the university is still not issuing the CAS within its own stated timescale, escalate in a structured way.

1. Contact the international student advice team, which is often separate from admissions and better placed to unblock CAS problems.

2. Put a clear, polite written request to a named manager, setting out the date you met all conditions, the university’s own service standard, and the practical deadline you face (the course start date and enrolment deadline). Ask for the CAS or a written explanation by a specific date.

3. Flag the practical constraint. A CAS generally must be issued far enough before the course start date for you to apply for and receive a visa in time. Universities are usually unwilling or unable to issue a CAS very close to the start date, so a delay can quietly become an effective refusal. Raising the deadline early puts pressure on the university to act.

If the university still fails to act, use its formal complaints procedure. Every university has one, and you should ask for it by name and follow its stages. Keep the complaint factual: dates, what you were told, what conditions you met, and what you are asking for.

If the university formally refuses the CAS

Ask for the refusal and its reasons in writing. Then consider whether the reason is one you can cure or challenge.

If the reason is a curable condition (for example a missing document or unpaid deposit), fix it and ask the university to reconsider.

If the reason relates to the university’s judgement about your credibility or ability to meet the visa requirements, ask what evidence would change its assessment. Universities are cautious here because issuing a CAS to someone who is then refused a visa affects their sponsor licence, so providing strong, well-documented financial and academic evidence can make the difference.

If you believe the refusal breaches the university’s own policy, misapplies its published criteria, or is otherwise unfair or based on an error, use the internal complaints procedure and ask for the decision to be reviewed.

The Office of the Independent Adjudicator (OIA)

Once you have exhausted the university’s internal complaints process, you can usually take an unresolved complaint to the Office of the Independent Adjudicator for Higher Education. The OIA reviews complaints from students at member higher education providers in England and Wales. You will normally need a Completion of Procedures letter from the university confirming the internal process is exhausted, and there are time limits for bringing a complaint to the OIA (generally twelve months), so do not delay.

There is an important limitation. Whether the OIA can consider your case may depend on whether you are treated as an applicant or an enrolled student, and the OIA generally deals with complaints from students rather than pure admissions decisions. If you are an offer-holder who has not yet enrolled, check the OIA’s current scheme rules on whether your complaint falls within its remit before relying on this route.

Consumer and regulatory routes

If the university has given you clearly misleading information, changed the rules after you accepted an offer, or applied unfair terms, you can raise this as a consumer complaint, referring to the Consumer Rights Act 2015 and the Competition and Markets Authority guidance for higher education providers. This can be used within your complaint to the university and, if needed, mentioned to the OIA.

Where the issue reflects a broader failure by the provider, you can also alert the Office for Students, though it regulates providers at a system level rather than resolving individual complaints.

If a delay or refusal means you cannot start on time

Be pragmatic about the calendar. If it is becoming clear the CAS will not arrive in time to obtain a visa before the enrolment deadline, ask the university directly about deferring to the next intake. A clean deferral with a fresh CAS for the later start date is often a better practical outcome than fighting for a CAS that can no longer realistically be used in time.

If you have already been refused a visa (as opposed to the university refusing a CAS), that is a different process. UKVI’s refusal notice will state the reasons and whether administrative review is available. To reapply you will need a new CAS, and the university will usually want to see the refusal reasons and evidence that a fresh application would succeed before issuing one.

Missing facts that change the answer

The right strategy depends on details you have not yet given, in particular: whether the CAS has been formally refused or merely delayed; the exact reason the university has given; whether you have met every published condition and paid any deposit; how close you are to the course start date and enrolment deadline; and whether you are an offer-holder or an already-enrolled continuing student. If you can tell me which of these applies, I can give you a more targeted set of steps and, if useful, help you draft the written request or complaint.

Practical next steps

1. Get the precise reason for the delay or refusal in writing.

2. Cure anything outstanding on your side immediately (deposit, documents, English evidence, interview).

3. If it is a genuine unreasonable delay, escalate in writing to a named manager, citing the university’s own service standard and your enrolment deadline.

4. If unresolved, use the formal internal complaints procedure and obtain a Completion of Procedures letter.

5. Consider the OIA within its time limits once internal procedures are exhausted, checking its remit for offer-holders.

6. In parallel, discuss deferral so you are not left with no route to study if the timing becomes impossible.

Keep a dated record of every contact, condition met, and promise made throughout, as this evidence is what will decide any complaint or review.
