How long do I have to apply for administrative review after a visa refusal?

The standard window is a short number of calendar days from the date of the refusal decision, and it is strict — missing it typically closes off the administrative review route entirely. Check the exact deadline stated on your own refusal letter, since timeframes can differ by application type and location.

Can I apply for both administrative review and judicial review at the same time?

Generally you should exhaust administrative review first where it is available, because judicial review is meant to be a remedy of last resort and courts expect other avenues to have been tried. Running both simultaneously without legal advice risks wasting the administrative review window or weakening the judicial review case.

Does administrative review look at new evidence I did not submit originally?

No. Administrative review is confined to the evidence that was before the original caseworker at the time of decision. If your refusal was caused by evidence you simply forgot to include, administrative review will not fix it — a fresh application is usually the better route in that scenario.

What is the difference between challenging a visa refusal and challenging an endorsement refusal?

A visa refusal is a Home Office immigration decision and is challenged through administrative review or judicial review as described in this article. An endorsement refusal comes from your endorsing body, not the Home Office, and is contested through that body's own internal appeal or reconsideration process, which is a separate track entirely.

Is judicial review likely to succeed if the Home Office simply disagreed with my business plan?

Unlikely on its own. Judicial review challenges the lawfulness of how a decision was reached, not whether the decision-maker's judgement call was the one you would have preferred. A caseworker being wrong in your opinion is not the same as a caseworker acting unlawfully, irrationally, or unfairly.

Administrative review vs judicial review after an Innovator Founder refusal

A refusal letter lands, and the instinct is either panic or a fast decision to "just appeal it." Neither response is quite right for a UK visa refusal, because there generally isn't a right of appeal for most points-based routes, including the Innovator Founder Visa. What exists instead are two narrower legal mechanisms — administrative review and judicial review — and they do genuinely different jobs.

This article is specifically about challenging a Home Office decision on your immigration application. If your problem is that an endorsing body declined to endorse your business, that is a separate track entirely — see appealing an endorsement refusal for that process, since endorsement decisions sit outside the Home Office's remit and are not touched by anything below.

Key rules

Most points-based visa refusals, including Innovator Founder refusals, carry no statutory right of appeal — the two available remedies are administrative review, which checks the original decision for caseworking error using only the evidence already submitted, and judicial review, which challenges the lawfulness of how the decision was made. Administrative review is faster, cheaper, and has a strict short application window; judicial review is slower, more expensive, requires permission from the court, and only succeeds where the decision was legally flawed, not merely one you disagree with. Choosing the wrong route wastes the short window most cases genuinely have to act. New evidence is not admissible in either process — if the refusal was caused by a documentation gap, a fresh application is usually faster than either remedy.

Why there is no simple "appeal" for most visa refusals

Historically, UK immigration decisions carried broad rights of appeal to a tribunal. Successive changes to the Immigration Rules narrowed that significantly, and today most points-based system categories, the Innovator Founder Visa among them, do not attract a full merits appeal. The refusal letter itself will normally state explicitly whether any appeal right exists for your specific decision, and for the overwhelming majority of Innovator Founder refusals it will not.

That absence of an appeal is precisely why administrative review and judicial review exist as the available checks on Home Office decision-making — they are narrower than an appeal, but they are not nothing.

What administrative review actually checks

Administrative review is an internal Home Office process in which a different, more senior caseworker re-examines the original decision. Crucially, it is confined to checking for case-working error — meaning the reviewer asks whether the original decision-maker misapplied the rules to the evidence that was actually submitted, missed a document that was in fact provided, or made a factual mistake such as misreading a bank statement's currency or date range.

It does not re-weigh a judgement call that was open to the original caseworker to make, and it does not consider evidence you did not submit the first time. If your Innovator Founder application was refused because a bank statement was genuinely missing from your submission, administrative review will not let you add it — the review is a check on the decision against what was in front of the decision-maker, not a second attempt at the application.

When administrative review is the right call

Administrative review fits situations like:

The caseworker's refusal letter cites a document as "not provided" when it was, in fact, included in the original submission.
A calculation error — for example, misreading the dependant financial requirement thresholds against the figures actually shown on your statements.
The refusal misstates a fact that is directly checkable against the submitted evidence, such as the wrong visa route being assessed against your application.

It is a relatively low-cost, fast mechanism precisely because it is narrow. It will not rescue an application that was refused because the underlying business case, evidenced correctly, simply did not meet the bar.

What judicial review actually checks

Judicial review is a different creature entirely. It is a claim brought in the courts — the Upper Tribunal handles the large majority of immigration judicial reviews in practice — challenging the lawfulness of how a decision was reached, not the correctness of the outcome in your opinion.

The recognised grounds are narrower than most applicants expect:

Illegality — the decision-maker misunderstood or misapplied the law or the Immigration Rules themselves.
Irrationality — the decision was so unreasonable that no reasonable decision-maker could have reached it (a genuinely high bar, not just "I disagree").
Procedural unfairness — you were not given a fair opportunity to respond, or the process itself was flawed, for instance if evidence was disregarded without explanation.

Judicial review is not a chance to re-argue your business case. It is a challenge to how the decision was made, not what the decision was.

— A frequent point immigration solicitors make to prospective clients

Judicial review requires the court's permission before the substantive claim is even heard, involves formal pre-action correspondence with the Home Office first, and carries meaningfully higher legal costs than administrative review. It also takes considerably longer — cases can run for months.

Choosing between the two

The practical decision tree most immigration solicitors apply looks roughly like this:

Is there an obvious factual or caseworking error checkable against your original submission? If yes, administrative review first — it is faster and cheaper, and in many cases must be tried before judicial review will be entertained.
Was the evidence you submitted actually correct and complete, but the decision still seems legally wrong — for example, a rule was misapplied, or you were not given a fair chance to address a concern before refusal? That points toward judicial review, ideally after taking specialist legal advice.
Was the refusal actually about the merits of your business case — the endorsing body or Home Office genuinely was not persuaded your innovation, viability or scalability evidence met the bar? Neither remedy is designed for this. A stronger fresh application, addressing the substance the caseworker was unconvinced by, is usually the faster and cheaper path back to a decision.

Cost and timeline, in practical terms

Administrative review carries a Home Office fee that is a small fraction of typical legal costs for a judicial review claim, and Home Office guidance targets a turnaround measured in weeks for most reviews, though this varies with caseload. Judicial review, by contrast, usually requires solicitor and (often) barrister involvement, court fees on top of any legal fees, and a timeline that commonly runs several months from pre-action letter to a permission decision, longer still if permission is granted and the case proceeds to a substantive hearing.

Given that gap, most immigration practitioners treat judicial review as a considered decision taken with legal advice, not a default reaction to a refusal — and treat administrative review as the fast, low-cost first check whenever the facts genuinely support it.

Getting specialist advice early

Because both routes have short, unforgiving deadlines, the most costly mistake is not choosing the wrong remedy — it is spending the deadline window deciding rather than acting. If your Innovator Founder application is refused, read the refusal letter immediately for the specific right (if any) it states you have, and consult an immigration solicitor before that window closes rather than after. A short paid consultation at the point of refusal is inexpensive compared with either missing a deadline entirely or running the wrong process and having to start again with a fresh application, which then requires meeting the current criteria from scratch — including any English requirement or documentation standard that may have tightened since your original submission.

Key takeaways

Most Innovator Founder refusals carry no statutory right of appeal — administrative review and judicial review are the two available remedies, and they do different jobs.
Administrative review checks for caseworking error using only the evidence already submitted; it cannot admit new evidence and has a strict short deadline, often just days.
Judicial review challenges the lawfulness of the decision-making process — illegality, irrationality, or procedural unfairness — not whether you disagree with the outcome.
Judicial review is slower, more expensive, requires court permission, and generally expects administrative review to have been tried first where available.
A refusal grounded in the actual merits of your business case is usually better addressed with a stronger fresh application than with either legal remedy.
Act immediately on receiving a refusal letter — both remedies have short, strict deadlines that do not extend for deliberation time.
