Listeners interested in traveling to the United Kingdom should be aware that, starting January 8, 2025, all U.S. citizens who do not have a UK visa or legal residency—including those merely transiting through UK airports—must obtain an Electronic Travel Authorization, or ETA. According to the U.S. Embassy London, the ETA is required for travelers of all ages, costs £10 (about $12.75), and can take up to three working days to process. This document is valid for two years or until your passport expires, whichever is sooner, and you do not need to specify travel details when applying. The ETA system is part of the UK’s transition to a full digital border and mirrors similar systems used by countries like the United States. If you hold a British or Irish passport, a valid UK visa, or an exempt vignette, you do not need to apply for an ETA. Citizens of countries that already require a visa to visit the UK will continue to need a visa and should not apply for an ETA. For full details and to apply, visit the official UK government guidance page.

For safety, travelers should exercise increased caution due to the ongoing risk of terrorism. The U.S. State Department and Government of Canada both warn that the UK remains at Level 2 advisory, meaning listeners should remain vigilant especially in crowded public areas, at tourist sites, airports, train stations, shopping centers, restaurants, and during major events or celebrations. Attacks in previous years have involved knives, vehicles, and explosives, mostly in London but occasionally elsewhere. The UK's current national terrorism threat level stands at “substantial”—meaning an attack is likely—while Northern Ireland’s separate level is “severe,” meaning an attack is highly likely.

Petty crime, such as pickpocketing and purse or cellphone theft, is common, especially in busy tourist locations in London. Travelers are advised to safeguard belongings and use licensed taxis or private hire vehicles, avoiding unmarked or unofficial transportation.

Medical care is widely accessible in the UK, though response times may vary outside major cities. Travelers should ensure health insurance covers international care and emergency services.

Faith-based travelers, members of the LGBTQ community, and those with disabilities are generally protected by UK law, which mandates reasonable accommodations, although transportation services may be excluded from some requirements.

Anyone planning to drive in the UK should remember that traffic flows on the left side of the road, different from the United States, and local traffic laws apply.

Finally, travelers should stay current on all recommended vaccinations, check the latest local air quality forecasts, and enroll in the Smart Traveler Enrollment Program for ongoing security updates while in the UK.

For more information or emergency support, listeners can contact local emergency services by dialing 999, consult the State Department’s travel page, or explore official UK resources for entry, health, and transport updates.
