University CAS allocation and UKVI compliance

This concerns the Home Office / UK Visas and Immigration (UKVI) student sponsor licence framework, which governs how universities and colleges are allowed to sponsor international students on the Student route. A zero CAS allocation and an action plan are two different UKVI compliance measures, though they often occur together. Here is what each means and what tends to happen in practice.

The underlying framework

To sponsor international students, an institution must hold a Student sponsor licence and appear on the Register of Student Sponsors. Its ability to bring in students depends on two things: its allocation of Confirmation of Acceptance for Studies (CAS), which are the electronic references a sponsored student needs to apply for a visa, and its compliance status under the Basic Compliance Assessment (BCA).

The BCA measures a sponsor against three core metrics each year: the visa refusal rate for sponsored applicants (must be below 10 per cent), the enrolment rate (at least 90 per cent of those given a CAS must actually enrol), and the course completion rate (at least 85 per cent must complete their course or have a valid reason for not doing so). Failing the BCA, or other compliance concerns arising from a UKVI visit or data check, is what usually triggers the measures you describe.

What a zero CAS allocation means

Each sponsor is given an annual CAS allocation. If UKVI reduces that allocation to zero, the institution cannot create any new CAS for the affected period, which means it cannot in practice sponsor any new international students until the position is resolved. Under the student sponsor compliance guidance, UKVI may “apply any limitations to a sponsor’s licence it considers appropriate”, expressly including limiting the number of CAS “to zero”.

A zero allocation is a restriction rather than an outright removal of the licence. Existing sponsored students who already hold a valid CAS and visa are generally not immediately affected, because their permission is already granted. The practical impact falls on prospective students and on new offers for the next intake. Institutions in this position often have to defer or withdraw offers, arrange refunds of deposits, and manage the reputational and financial fallout.

Importantly, a zero CAS allocation is not necessarily permanent. It can be increased again once UKVI is satisfied that the underlying concerns have been addressed, often after the sponsor has completed an action plan or passed a further assessment.

What an action plan means

An action plan is imposed where UKVI considers the sponsor has committed a breach that falls short of a serious breach warranting immediate revocation. The purpose, in UKVI’s own words, is to give the sponsor an opportunity to improve its processes so that further breaches are avoided and revocation does not become necessary.

Key features of an action plan are as follows. It sets out specific steps the sponsor must take and a timescale for doing so, typically lasting between three and six months. The sponsor must pay a fee for being placed on the plan. Crucially, while the action plan is in force, UKVI may impose limitations on the licence, and this is exactly where the two measures overlap: a zero or reduced CAS allocation is a common limitation applied during an action plan. The sponsor’s status on the Register of Student Sponsors may also change to reflect that it is not currently a fully compliant “Student sponsor” with a track record.

If the sponsor completes the action plan satisfactorily, the limitations are lifted and normal sponsorship resumes. If it fails to meet the plan, or if further or more serious breaches emerge, UKVI can escalate to suspension and ultimately revocation of the licence.

How this differs from suspension and revocation

It is worth distinguishing these measures from the more serious steps, because the consequences differ sharply.

A reduced or zero CAS allocation and an action plan are corrective and usually recoverable. Existing students are generally protected and the licence continues.

Suspension is more serious. When a licence is suspended pending investigation, the sponsor cannot issue any new CAS during the suspension, and UKVI investigates before deciding whether to reinstate, downgrade or revoke.

Revocation is the most serious outcome. Losing the licence entirely means the institution can no longer sponsor students at all. Existing students then typically have their permission curtailed, usually being given a limited period (commonly 60 days) to find a new sponsor, apply under a different route or leave the UK, unless a transitional arrangement applies. This is why an action plan is framed as an opportunity to avoid getting to that point.

Practical consequences for the institution and its students

For the institution, the immediate consequences of a zero allocation or an action plan are operational and financial. It cannot recruit new international students while the restriction lasts, it must divert resources into remedying the compliance failings identified, it pays the action plan fee, and it faces reputational risk once the change in status becomes visible on the register or in the press. It will normally need to demonstrate improved systems for record-keeping, monitoring attendance and engagement, tracking visa outcomes, and reporting changes to UKVI.

For current students already holding valid visas, there is usually no immediate change, and they can continue their studies. The risk to existing students only becomes real if matters escalate to revocation.

For prospective or newly offered students, a zero allocation is the critical problem, because no CAS can be issued. Offers may be deferred to a later intake, conditional on the licence position being restored, or withdrawn, and any deposits paid should ordinarily be refundable if the institution cannot deliver sponsorship. If you are an applicant in this situation, you would be relying on the institution’s admissions terms and on general consumer protection principles regarding refunds where the service cannot be provided.

What the institution can and should do

If you are acting for or within the institution, the sensible sequence is broadly as follows.

1. Obtain and read the UKVI correspondence carefully, identifying the precise concerns, the metrics or breaches relied on, the exact terms of any action plan, and all deadlines.

2. Engage constructively and promptly with UKVI, because these processes reward cooperation and evidence of remediation, and missed deadlines can escalate matters quickly.

3. Carry out an internal audit of sponsor compliance duties, focusing on the areas UKVI has flagged and on the BCA metrics, and document the improvements made.

4. Take specialist immigration and public law advice at an early stage, because the framework is detailed and the consequences of getting it wrong are severe.

5. Where a decision such as suspension or revocation appears legally flawed, consider the available challenge routes. Sponsor licensing decisions are generally not subject to a statutory appeal, so the principal remedy is judicial review of the UKVI decision, which has strict time limits and requires the decision to be shown to be unlawful, irrational or procedurally unfair rather than merely harsh.

Key missing facts

The precise position depends on several things you have not stated: whether you are asking as the institution, a current student, or a prospective applicant; whether the measure in question is a reduced allocation, a zero allocation, an action plan, a suspension, or revocation; the specific breaches or BCA failures UKVI has identified; and the exact wording and deadlines of the UKVI letter. These details materially affect both the consequences and the appropriate response, so any concrete strategy should be built around the actual UKVI correspondence.
