From the start of 2025, Mexican travelers must apply for an Electronic Travel Authorization (ETA) before visiting the UK.
Without an approved ETA, you won’t be allowed to board your flight or enter the UK, even for short visits.
What is the UK ETA, and why do Mexicans need it?
The UK ETA is a new digital entry requirement, not a visa, designed to strengthen border security.
Can Mexicans still travel to the UK without a visa?
Mexican passport holders don’t need a traditional visa for short stays, but the ETA is now mandatory for visits to England, Scotland, Wales, and Northern Ireland (not the Republic of Ireland).
If you’re just transiting through the UK, an ETA is not required.
💡 However, Mateo Martinez, travel blogger, says:
"The rules around whether you need a UK ETA if you're just transiting through keep changing, so it's worth double-checking before you fly."
How to apply for a UK ETA fast
Follow these steps to secure your UK ETA:
1️⃣ Submit your details: Apply via the UK government website or use our online platform or mobile app.
Provide personal and passport information, along with a clear digital passport photo.
2️⃣ Pay the ETA fee: Secure payment options include debit/credit cards, PayPal, and other flexible online methods.
3️⃣ Receive approval: Most applications are approved within 72 hours, though some are processed even faster.
Once approved, the ETA is electronically linked to your passport, so there’s no need to print anything.
How long can Mexicans stay in the UK with an ETA?
The UK ETA allows Cypriot visitors to stay for up to six months per visit for tourism, business, or family visits.
It's valid for two years or until your passport expires, whichever comes first. A new passport means reapplying for the ETA.

💡 Andreas Christoforou, immigration lawyer, advises:
"Mexicans should apply well in advance, especially during peak travel times like summer. Many don’t realize last-minute applications can be risky."
Other important UK entry rules
Even with an ETA, travelers should be aware of additional UK entry regulations:
- Proof of onward travel – You may need to show your return ticket.
- Customs restrictions – Be mindful of duty-free allowances and prohibited items.
