Since in-country switching from Student to Innovator Founder opened, a new kind of avoidable problem has appeared: applicants who meet every business requirement but cannot show they have finished their course. The endorsement is in place, the plan is strong, and the application stumbles on a date.

This article covers what Home Office caseworker guidance says about course completion, how to evidence it, and the wider validity checks that can turn a strong application into a rejected one.

The completion rule in plain terms

SituationWhat the guidance requires
Undergraduate or taught postgraduate studentCompleted the course on the CAS, or one covered by ST 27.3 of Appendix Student
PhD studentCompleted at least 12 months of the PhD

The starting point is your CAS, the document your university issued for your Student visa. Caseworkers check the course end date on it. If that date has passed, the check is usually straightforward.

The difficulty comes when your course effectively finished before the CAS end date, which can happen when results are confirmed before the formal end date. The guidance allows for this: caseworkers may accept earlier completion shown by, for example, a results transcript.

Mistake 1: Assuming the caseworker will work it out

If you apply before the CAS end date, the caseworker will see a course that, on paper, has not finished. The guidance says they may accept earlier completion, which means it is discretionary and depends on evidence. Do not leave it to chance.

If you are applying before the CAS end date, include evidence of completion with the application. The guidance names a results transcript as an example. A clear document from your university confirming that you have completed the course is the kind of thing that helps a caseworker reach the right conclusion quickly.

Mistake 2: Confusing "results pending" with "completed"

Handing in a dissertation is not necessarily the same as completing a course. If your final results have not been confirmed, you may not yet be able to evidence completion. Check with your university what document it issues on completion and when.

This matters for timing. Your endorsement letter must be issued no more than 3 months before you apply. If you obtain an endorsement in May but cannot prove completion until September, the letter may have expired before you can use it. See timing your switch around the 3-month window.

Mistake 3: Applying from a category that cannot switch

Short-term Student is on the list of routes that cannot switch to Innovator Founder in-country, along with Visitor and several others. Completing a short course on that route does not open the in-country switch. You would need to apply from outside the UK. Read who cannot switch to Innovator Founder before you start.

If, in the 12 months before applying, you held a government or international scholarship agency award covering both fees and living costs for UK study, you need that sponsor's written consent. This is easy to forget once the course has ended. See the scholarship sponsor consent rule.

Mistake 5: Overlooking the basic validity requirements

Course completion is an eligibility point. Separately, the application must be valid in the first place. Caseworker guidance lists:

  • the fee and the Immigration Health Charge paid
  • biometrics provided
  • a passport
  • an endorsement letter issued no more than 3 months before the application date, and not withdrawn
  • the applicant aged 18 or over

For missing items that can be fixed, such as the Immigration Health Charge not being paid for the full period, the guidance says caseworkers normally write to the applicant to give them the chance to fix it. That is helpful, but it adds delay and uncertainty. Treat it as a safety net only.

Mistake 6: Letting your Student permission lapse while you wait

Waiting for results or a completion letter can push you close to your Student visa expiry. Applicants must not be in breach of immigration law, apart from limited overstaying exceptions, and anyone on immigration bail does not meet the suitability requirement except where the Rules allow. Apply while your current permission is valid.

The cost of getting it wrong

An in-country Innovator Founder application costs £1,693 per person, plus the healthcare surcharge. If it is refused, there is no appeal. Administrative review is available, and the Home Office fees table lists it at £80, but it adds time and uncertainty. Getting the completion evidence right first time is far cheaper.

A short pre-submission checklist

  • CAS course end date noted, and passed, or evidence of earlier completion ready
  • PhD students: evidence of at least 12 months of the PhD
  • Not on a route barred from switching
  • Scholarship sponsor consent, if relevant
  • Endorsement letter dated within 3 months of the application date
  • Fee, healthcare surcharge, biometrics and passport in order
  • Current permission still valid on the day you apply

Key takeaways

  • Students must have completed the course on their CAS before switching; PhD students need at least 12 months of the PhD.
  • Caseworkers check the CAS end date but may accept earlier completion shown by evidence such as a results transcript.
  • If you apply before the CAS end date, include completion evidence and explain it.
  • Validity requirements, including an endorsement letter no more than 3 months old, apply separately from course completion.
  • A refused in-country application has no appeal, only administrative review, so get the evidence right first time.
