From 1 June 2026, universities and other Student sponsors have been working under tighter Home Office compliance rules. The practical result is simple. Your chosen institution may check your Student visa application more closely before it issues your Confirmation of Acceptance for Studies, known as a CAS.
The rules do not change who qualifies for a Student visa. They change how cautious a university is likely to be before it sponsors you. If the institution issues a CAS and your visa is refused, or you do not enrol, that can affect its sponsor compliance record.
What has actually changed
Every university that recruits international students needs a Student sponsor licence. To keep that licence, it must apply for a Basic Compliance Assessment, or BCA, every 12 months. If you want a refresher on the visa route itself, our guide to UK student visa requirements sets out the basics.
The Home Office has tightened 2 of the 3 core BCA thresholds for assessments applied for on or after 1 June 2026. Visa refusal rates must now be below 5%, down from below 10%. Enrolment rates must reach at least 95%, up from 90%. The course completion threshold remains at 85% for now, then rises to 90% for assessments applied for on or after 1 June 2027.
You can check the detail in the Home Office student sponsor guidance.
| BCA metric | Previous threshold | From 1 June 2026 |
| Visa refusal rate | Below 10% | Below 5% |
| Course enrolment rate | At least 90% | At least 95% |
| Course completion rate | At least 85% | 85% until 31 May 2027, then 90% from 1 June 2027 |
There is also a new Red-Amber-Green rating system. It does not work as an average across all 3 metrics. A sponsor’s overall rating is driven by its weakest metric. So a university with strong enrolment and completion figures can still face problems if its visa refusal rate is too high. We explain how this works for institutions in our note on sponsor licence compliance in 2026.
Why this lands on your application
Look at it from the university’s side. Every refused application now carries more weight. A sponsor sitting near the 5% refusal threshold has little room for avoidable mistakes, so admissions and compliance teams have a strong reason to screen applicants harder before issuing a CAS.
That does not mean genuine students should panic. It means your documents need to be clean, consistent and ready before the university reviews them.
Here is a simple example. Two applicants apply for the same Master’s course, and both are genuine. One has clear financial evidence, a credible academic history and a sensible study plan. The other has funds that appeared very recently, an unexplained study gap and inconsistent information across documents. In 2025, the second applicant might have been asked fewer questions. In 2026, a cautious sponsor may pause, request more evidence, or decline to issue the CAS.
The same pressure runs across the wider work sponsorship system, as our skilled worker sponsor licence guide explains.
What students should prepare earlier
Before asking for a CAS, check that your financial evidence meets the Student route rules, your course progression makes sense, and your personal details match across every document. If you have a study gap, past refusal, unusual funding source or change of course direction, prepare a clear explanation before the university asks for it.
Plenty of students later move into work routes, where the rules are also tightening, as our note on skilled worker visa eligibility shows. Others consider the self-sponsorship route once they are established in the UK.
For now, the priority is getting the first application right. If you want your documents reviewed before you risk a refusal or CAS delay, we offer practical UK student visa application support.
Frequently asked questions
Do the June 2026 rules change Student visa eligibility?
No. They change the compliance thresholds for sponsors, not the core Student visa requirements.
Why might a university ask for more documents?
Because refused visa applications and non-enrolments can affect its sponsor record. Extra checks help protect both the student and the institution.
Can a university refuse to issue a CAS?
Yes. A university does not have to issue a CAS if it is not satisfied that the application is credible or properly evidenced.
Does the 90% completion threshold apply now?
Not yet. The completion threshold remains 85% for assessments applied for from 1 June 2026 and rises to 90% from 1 June 2027.
