March 20, 2025 – Travelers planning trips to the United States should prepare for new challenges as multiple countries update their travel advisories, warning citizens about recent changes to U.S. immigration policies. The updated alerts highlight increased border checks, tighter visa restrictions, and new rules regarding gender designation that could significantly impact foreign visitors.
The growing list of concerned nations includes Canada, the U.K., Germany, France, and several others. These countries are cautioning their citizens about several key issues that have emerged in recent weeks. Travelers now face stricter border controls, with reports of increased detentions and deportations even for those holding valid visas. A particularly notable change requires visitors staying more than 30 days to register as “aliens” with U.S. authorities starting April 11.
Another major concern involves gender designation rules. Travelers with “X” gender markers in their passports or those who have legally changed their gender must now declare their birth-assigned sex when applying for U.S. visas. Discrepancies between travel documents and birth records could lead to denied entry. Border agents have also intensified enforcement of visa rules, leading to arrests for what some travelers describe as minor violations.
The list of countries issuing warnings continues to grow. Belgium has warned its citizens about both immigration crackdowns and potential challenges for LGBTQ+ travelers. Canada has specifically highlighted the new 30-day registration requirement, while Denmark and Finland have focused on risks for travelers with non-binary gender markers in their documents. France’s advisory details the stricter gender declaration rules now in place for visa applications.
Germany’s warning comes after several German tourists were detained despite having valid travel authorization. Ireland and the Netherlands both emphasize the importance of having perfect documentation, noting that even small errors can result in denied entry. Norway and Portugal remind travelers that possessing a visa doesn’t guarantee admission to the U.S., as border officials have final authority. The U.K. has strengthened its guidance after multiple British citizens faced detention for alleged visa violations.
For travelers, these developments mean taking extra precautions. Experts recommend double-checking all visa requirements well in advance of travel dates. Those with non-binary gender markers should verify their status with U.S. authorities before departure. Visitors planning stays longer than 30 days must prepare to comply with the new registration rule taking effect in April. Most importantly, travelers should monitor their home country’s travel advisories for any updates.
These warnings reflect broader changes in U.S. immigration policy following a recent executive order. While officials say the measures are necessary for security, critics worry about the potential impact on tourism, business travel, and international relations. With the situation evolving rapidly, more countries may join the advisory list in coming weeks. Travelers are advised to stay informed and prepare thoroughly to avoid problems at U.S. borders.
