As geopolitical tensions impact travel, the U.S. Department of State continues to actively update its travel advisories, from changes to travel warnings for five countries in a single day to a series of security alerts about attacks targeting U.S. citizens.
Over the past week, the U.S. Embassy in London issued a new warning about threats to “American interests,” including tourist locations, in the United Kingdom. The U.K. consistently ranks among the top vacation destinations for Americans, with the U.S. as the leading tourism market for the U.K.
Here’s the State Department’s latest travel advice for Americans planning to visit the U.K.
U.S. State Department Warns Of Attacks Targeting American Travelers In The U.K.
On April 24, the U.S. Embassy in the U.K. issued a security alert about “recent attacks and threats targeting Jewish and American institutions,” not only in the U.K. but also across Europe. This follows a previous warning about Iran-linked groups targeting Americans in the “Maldives of Europe.”
U.S. citizens are advised to remain vigilant and exercise increasing caution in the U.K., particularly when visiting institutions that serve Jewish or American interests, such as tourist locations, community centers, and places of worship.
U.S. Maintains Level 2 Travel Advisory For The U.K.
The U.S. maintains a Level 2 travel advisory for the U.K., urging travelers to “exercise increased caution” due to the risk of terrorism. The advisory summary identifies the following as common targets for terrorist attacks in the U.K.:
- Tourist sites
- Transportation hubs, including airports
- Markets and shopping malls
- Local government facilities
- Hotels, clubs, and restaurants
- Religious sites or places of worship
- Parks
- Major sporting and cultural events or concerts
- Educational institutions
- Other public areas
The State Department reminds U.S. citizens to enroll in the Smart Traveler Enrollment Program (STEP) to receive alerts and make it easier to reach them in an emergency. Americans heading to the U.K. are also advised to get travel insurance with evacuation assistance, medical insurance, and trip cancellation coverage.
New Entry Requirements U.S. Travelers Heading To U.K.
U.S. citizens now need an Electronic Travel Authorisation (ETA) to enter the U.K. for tourism, study, business, or transit, whether they are traveling by air, land, or sea. American travelers without an approved ETA could be denied boarding by their airlines or refused entry at the U.K. border.
U.K. Entry requirements for dual citizens: U.S. citizens who hold British or Irish citizenship do not need a U.K. Electronic Travel Authorization (ETA). However, they should have a valid U.K. or Irish passport or certificate of entitlement when traveling to the U.K. You may be denied boarding without a valid U.K. passport.
The ETA allows Americans multiple entries into the U.K., for stays up to six months at a time over two years or until their passport expires (whichever is sooner). To secure an ETA, only apply via the official “UK ETA App,” which is available on Google Play and Apple App Store, at least three working days ahead of your trip.
Step-By-Step ETA Application Process
- Pay the £20 ETA fee via credit card, Apple Pay, or Google Pay
- Submit contact and passport details
- Provide a valid photo (check GOV.UK’s rules for digital photos)
- Answer a set of suitability and criminality questions
- Travel using the same passport used for the ETA application
Most U.K. ETA applicants get an automatic decision within minutes of submitting their application. However, some cases may need further review for things like identity verification and checking security or immigration databases for adverse information like criminal records.
Once approved, the U.K. ETA is digitally linked to the traveler’s passport and automatically confirmed when the passport is scanned at e-gates or with a border officer.
U.S. Remains Top Tourist Market For The U.K.
The U.S. remains the U.K.’s leading tourism market. In 2024 alone, the U.K. welcomed a record 5.6 million visits from the U.S., leading to a record £7.3 billion (nearly $10 billion) in total expenditure and an average spend of £1,301 (approx. $1,770) per visit. Among the cited appeals of U.K. vacations for Americans are the shared language, ease of travel, and deep cultural and historical ties.
Visit Britain reports: “The UK was ranked third by Americans for historic buildings and contemporary culture, and fifth for culture in general and would visit if money was no object. Americans also ranked the UK in the top ten for people, tourism, sport, vibrant city life/urban attractions, cultural heritage, and welcome.”
According to Visit Britain’s data, London remains the leading destination for U.S. travelers visiting the U.K., with 48% of their nights spent in England’s largest and capital city. Americans mostly visit for holiday purposes, accounting for 2.9 million visits to the U.K. in 2024.
Six in ten American holiday visitors are planning a repeat trip. Most U.S. visitors to the U.K. are older (age 55+), making up 30% of all U.S. tourists, while overall visits are mostly from the New York Tri-State (19%) and California (15%).
The U.K. also remains one of the top-spending visitors in the U.S. However, the U.K. government’s recent warnings on stricter U.S. border requirements may be scaring some Brits away.
