If my endorsing body already assessed me, why does the Home Office check genuineness again?

Endorsement and immigration decision-making are legally separate functions. The endorsing body assesses whether the business idea is innovative, viable and scalable; the Home Office caseworker, applying the Immigration Rules, separately assesses whether you personally are a genuine entrepreneur intending to run that business — the two questions overlap in evidence but are decided by different people against different legal tests.

Can a caseworker refuse my visa even with a valid endorsement letter?

Yes. An endorsement letter is a mandatory requirement, not a guarantee of approval. The Immigration Rules give the Home Office an independent discretion to refuse where the genuine entrepreneur requirement isn't met, most commonly exercised where the caseworker has specific, articulated doubts about the application's credibility.

What triggers a genuine entrepreneur interview?

There's no published fixed trigger list, but common factors include inconsistencies between the application and the endorsed business plan, a business model the caseworker doesn't understand well enough to assess on paper, or a profile that doesn't obviously match the stated business (for example, no demonstrable connection to the sector).

Is the genuine entrepreneur test different from the endorsing body's own genuine entrepreneur assessment?

Yes, and this is the most commonly confused point. Endorsing bodies run their own internal genuine entrepreneur assessment as part of deciding whether to endorse you at all — that's a business-judgement exercise. The Home Office's genuine entrepreneur requirement in the Immigration Rules is the separate, legal test a caseworker applies when deciding the visa application itself.

The genuine entrepreneur requirement in the Immigration Rules, explained

Every Innovator Founder Visa application clears two genuine entrepreneur checks, not one, and conflating them is one of the more common sources of confusion for founders navigating the process. The first is run by the endorsing body, as a business-judgement exercise, before they'll agree to endorse you at all — that process is covered in detail in the genuine entrepreneur test, decoded. The second is written directly into the Immigration Rules and is applied independently by a Home Office caseworker when they decide the visa application, endorsement letter in hand or not.

This article is about the second one — the rules-based test, not the endorsing body's internal assessment.

Key rules

Appendix Innovator Founder gives Home Office caseworkers an independent power to refuse an Innovator Founder Visa application on genuine entrepreneur grounds even where a valid endorsement letter has been issued. The test looks at whether the applicant genuinely intends to establish, take over, or become a director of the specific business described, whether the money and resources claimed are genuinely available and under the applicant's control, and whether the overall application is credible given the applicant's immigration history, background, and the plausibility of the business itself. A caseworker who has doubts can request further information, invite the applicant to interview, or refuse outright with reasons. This test is separate from and additional to the endorsing body's own assessment — an endorsement letter is necessary for the application but is not, on its own, sufficient to satisfy the Home Office that the applicant is a genuine entrepreneur under the Rules.

Where the test actually sits in the Rules

The genuine entrepreneur (and genuine investment, for related historical routes) requirement has been a feature of UK entrepreneur-category visas for years, predating the current Innovator Founder route, and it survived the 2023 reforms that replaced the old Innovator and Start-up categories. In the current Immigration Rules, it sits within Appendix Innovator Founder as a suitability-adjacent requirement the decision-maker must be satisfied of, distinct from the endorsement requirement itself.

What a caseworker is actually checking

Based on the structure of the requirement and the pattern of published Upper Tribunal decisions on predecessor routes (the genuine entrepreneur test is not new to Innovator Founder — it has a substantial case-law history under the old Tier 1 Entrepreneur and Innovator categories), the assessment generally covers:

Genuine intention to run the specific business

The caseworker is checking whether you intend to actually establish, take over, or become a director of the business described in your endorsement — not a different business, and not no business at all. This sounds obvious, but historically this is where refusals have concentrated: applicants whose account of the business at interview didn't match the written plan, or who couldn't explain basic operational details of a business they claimed to have designed.

Availability and control of funds

Where the business requires investment funds, the caseworker checks that the money is genuinely available to the applicant and under their control — not borrowed for the purposes of the application and due to be returned, not contingent on events that haven't happened, and not somebody else's money presented as the applicant's. This is a long-standing feature of UK entrepreneur-route scrutiny and one of the most litigated points under predecessor categories.

Credibility of the applicant's background against the business

A caseworker will weigh whether the applicant's stated background — education, work history, sector experience — is plausible against the business being proposed. This isn't a formal requirement that you must have direct sector experience (many genuinely innovative founders enter a sector they haven't worked in before), but a wide, unexplained gap between background and business can prompt further questions rather than an automatic refusal.

The government have said 'hey you can come into the UK to build your business' but your half of the contract is that you build that business — that's what you signed up to.

— Richard Harrison, Innovator International

That framing — endorsement as a contract you're expected to actually perform — is exactly what the genuine entrepreneur requirement is designed to police at the point of the visa decision, before the contract even begins.

Consistency with the endorsed plan

Caseworkers can and do compare what's in the visa application against what the endorsing body assessed. Material inconsistencies — a different business model, a different investment figure, a different founding team — between the endorsement documentation and the visa application are a red flag precisely because the endorsement is meant to certify the same business the applicant is asking to be granted leave to pursue.

What happens when a caseworker has doubts

The Rules and standard Home Office practice give caseworkers a few tools short of immediate refusal:

Requesting further information or evidence — a written request for clarification, additional documents, or explanation of a specific point.
Inviting the applicant to interview — a genuine entrepreneur interview, conducted to test the applicant's knowledge of and intentions toward their own business plan. This is the same mechanism used historically under Tier 1 Entrepreneur and Innovator, and case law from those routes (while not binding precedent for Innovator Founder specifically) illustrates the kind of questioning that has occurred — detailed operational questions about the business that a genuine founder should be able to answer without hesitation.
Refusal with reasons — where the caseworker isn't satisfied after any further information or interview, the application is refused, and the applicant has the standard routes of challenge (administrative review, and in some circumstances judicial review) available depending on the specifics of the refusal.

Why this matters even if you have a strong endorsement

A strong, well-prepared endorsement application reduces but does not eliminate genuine entrepreneur risk. The two most common ways a well-endorsed applicant still runs into trouble at this stage are: presenting to the Home Office a business plan that has quietly evolved since endorsement without flagging the change, and being unable to speak fluently about operational details of the business at an interview because the plan was heavily written by advisors rather than genuinely understood by the founder.

How this differs from a rejected endorsement or a refused visa on other grounds

A rejected endorsement application happens before this stage entirely — it's the endorsing body declining to certify the business, and the Home Office genuine entrepreneur test never gets applied because there's no application to assess yet. This article's test only comes into play once you have a valid endorsement and have submitted the actual visa application. If that application is refused specifically on genuine entrepreneur grounds, the options and process for appealing an endorsement refusal don't directly apply, since that refusal sits with the Home Office rather than the endorsing body — administrative review of the visa decision is the more relevant route, and it's worth getting immigration solicitor advice quickly given the tight deadlines involved.
