How UKEntryCheck works
UKEntryCheck is a rules-based browser helper. It does not query government systems or store user profiles. Instead, it maps a small set of high-value questions to the current public GOV.UK ETA guidance pages reviewed on 2026-04-24.
Rule order
- It first checks common no-ETA conditions, such as British or Irish citizenship, an existing UK visa, or permission to live, work, or study in the UK or certain Crown Dependencies.
- It then checks passport-type exceptions, airside transit without border control, certain Ireland-route cases, and other listed special exceptions.
- If no exception applies, it checks whether the passport nationality is on the current ETA-eligible list published on GOV.UK, including the Taiwan passport ID-number condition.
- It then checks whether the selected trip purpose fits the ETA-covered visit types published by GOV.UK.
- If the passport or purpose does not fit the ETA path, the tool routes the user toward the official GOV.UK visa checker.
What the tool does well
- It compresses several GOV.UK ETA pages into one faster first-pass decision flow.
- It surfaces common exceptions that travellers often miss, especially UK permission and airside transit cases.
- It always points the user back to the relevant official GOV.UK page for the next step.
What the tool does not do
- It does not replace the official visa or ETA application systems.
- It does not guarantee entry, issue legal advice, or cover every immigration edge case.
- It does not evaluate document validity, criminal-record issues, or other admissibility factors outside the published ETA guidance.
