Its Foreign Office also warns about terrorism and crime, as well as unstable politics, stating, “there remains a heightened risk of politically motivated violence.” At the top of its page is also advice about the US wildfire season from June to December, especially in California, Washington, and Oregon.
Ireland
Ireland updated its travel guidance for the US on March 28, 2025 to include advice for transgender Irish citizens, stating: “ESTA and visa application forms to the US require travelers to declare their sex. The US authorities have indicated that this should reflect, what they term, the traveler’s biological sex at birth.”
“Previous convictions in the United States, misleading information about the purpose of your stay on your visa or ESTA application, or even a slight previous overstay can have serious consequences,” Ireland’s Department of Foreign Affairs’s site reads. That said, they do note the “vast majority” of travelers don’t encounter issues.
It also notes that the US states of Arizona, Utah, Indiana, South Carolina, Georgia, and Alabama have introduced legislation to combat illegal immigration that authorizes “police officers to seek information on an individual’s immigration status and to detain people they suspect of being in the US illegally.” They suggest that travelers carry their documents with them at all times in case they are asked to present them by law enforcement officials.
Netherlands
While the Dutch ministry of foreign affairs still has the US listed as green in its level for safe travel, its travel advice page was last modified on April 4 including: “Please note that laws and customs in the US towards LGBTQ+ persons may differ from those in the Netherlands.” No further updates have been made since then.
New Zealand
Unlike most countries on this list, New Zealand actually increased the US travel advisory level on its official four-level scale. Last November, it bumped the US to Level 2, advising New Zealanders to “exercise increased caution,” a warning that remains today.
Specifically, it states that there is a “higher incidence of violent crime and firearm possession than in New Zealand,” highlighting a risk of active shooter incidents as well as petty crime. Like Australia, it also tells its citizens to register if staying more than 30 days and to have photo IDs that meet REAL ID standards. The site also notes that “the US government has strict rules for entering and staying in the country” and says that “you may encounter scrutiny from US border authorities” upon arrival.
Portugal
Portugal’s Ministry of Foreign Affairs updated its travel guidance for citizens visiting the US, noting: “Possession of an ESTA or visa does not automatically entitle you to entry into the US. The final decision is always made by the border agent upon arrival in the United States.” It also advises non-binary travelers to “complete forms and provide declarations upon arrival with the gender with which they were identified at birth.”
The Portuguese government also highlights certain areas of the country for safety risks, including neighborhoods of Washington, D.C., Boston, Philadelphia, and San Francisco, as well as Baltimore, which it labels as “a dangerous city, except for the city center.” As for New York City, it says that after dark, visitors should only visit Central Park, Harlem, and the Bronx in groups.
United Kingdom
The UK updated its US travel advisory for British travelers bound for America with stricter wording: While in February, it stated, “the authorities in the US set and enforce entry rules,” the language was changed in March to say those rules are enforced “strictly,” which remains on the site at the time of going to press.
“They’re basically telling people to double check the requirements because it’s very difficult to pinpoint any specifics right now,” Yu says, citing the examples of European travelers, including a UK national, being detained at the border. “It’s a very general advisory: Do your homework and if you aren’t sure, check with the US embassy.”
On June 11, additional information was added to make British citizens aware of protests happening across the nation, broadly stating: “No travel can be guaranteed safe.”
