Seventeen U.S. embassies across Europe have launched a coordinated campaign warning foreign nationals about heightened risks of detention and deportation, even if they possess valid visas or green cards.
Key Insights
- Multiple European countries and Canada have issued formal travel advisories warning citizens about increased U.S. immigration enforcement and potential deportation risks.
- A valid visa no longer guarantees entry into the United States, with border officials exercising broad discretion to deny entry or revoke immigration status.
- Foreign nationals involved in political protests, particularly related to the Gaza conflict, face heightened scrutiny with documented cases of visa revocation and deportation.
- The U.S. has implemented stricter documentation requirements, including the suspension of the “X” gender marker on passports and mandatory registration for stays exceeding 30 days.
- Electronic device searches at points of entry have increased, with social media content potentially used as grounds for denial of entry.
European Nations Sound the Alarm
Denmark, the United Kingdom, Germany, Finland, and Canada have all updated their travel advisories for citizens planning to visit the United States. These warnings follow a pattern of increased enforcement actions at U.S. borders, including detentions and deportations of foreign nationals who previously would have been admitted without issue. The United Kingdom explicitly warns travelers that non-compliance with entry requirements may lead to “arrest or detention,” regardless of visa status.
The U.S. State Department has implemented significant policy changes affecting travelers, including the suspension of procedures allowing transgender, intersex, and nonbinary individuals to update the sex field on their passports. Both Denmark and Finland have specifically updated their guidance to reflect that U.S. authorities now recognize only two sexes in travel documents. Canada has emphasized that visitors staying longer than 30 days “must be registered with the United States Government.”

Targeted Enforcement Against Political Activity
The Trump administration has particularly focused enforcement efforts on international students and professors involved in protests related to the Gaza conflict. Actions have included revoking visas, detaining visa holders at ports of entry, and blocking entry altogether. U.S. embassies in at least 17 European countries are using social media to warn potential visitors about behaviors that could lead to deportation, featuring images of President Trump, Secretary of State Marco Rubio, and Homeland Security Secretary Kristi Noem.
“Follow the law, behave yourselves, be a good visitor and you’ll be fine. It’s a visa. It’s not an entitlement. A visa and a green card are not birthrights. These are privileges you’re granted … because of what you present to the United States,” said State Department spokeswoman Tammy Bruce.
State Department spokeswoman Tammy Bruce has emphasized that visas are privileges rather than entitlements. Secretary of State Marco Rubio has stated that the administration doesn’t want people “committing crimes and undermining our national security or public safety.” Homeland Security Secretary Kristi Noem has warned foreign nationals that those who entered under false pretenses to participate in campus protests would be removed from the country.
Practical Advice for Travelers
Immigration experts recommend foreign nationals take several precautions when traveling to the United States. Travelers should carry comprehensive documentation proving their eligibility for entry and ensure full compliance with all immigration requirements. Those with prior arrests or legal issues should consult an immigration attorney before attempting to enter the U.S. All travelers should be prepared for potential searches of electronic devices by Customs and Border Protection officers.
According to assistant commissioner of public affairs at U.S. Customs and Border Protection Hilton Beckham, “Foreign nationals who promote extremist ideologies or carry terrorist propaganda are inadmissible to the U.S., plain and simple. A visa does not guarantee entry; CBP has the final authority after conducting rigorous security checks.”
While most foreign nationals with proper documentation continue to be admitted without issue, there are increasing reports of questionable decisions by Department of Homeland Security and Customs and Border Protection officials. The economic impact of these advisories remains uncertain, though some tourism experts have raised concerns about potential declines in travel and spending from Western European visitors who traditionally constitute a significant portion of foreign tourism revenue.
