Spain has updated its travel information for those heading to the U.S., with new advice for transgender travelers.

Newsweek contacted Spain’s foreign ministry for comment via email on Monday.

Why It Matters

Spain is the latest European nation to update such information for its citizens travelling to the U.S.

Many have already done so, including Britain and Germany, seemingly in reaction to President Donald Trump‘s sweeping crackdown on illegal immigration and transgender rights.

What To Know

Spain’s travel information, updated on April 10, notes that travelers must indicate their gender on the Electronic System for Travel Authorization (ESTA) and U.S. visa application forms.

Under recent U.S. government policies, this information must now correspond to the individual’s biological sex at birth, it notes.

Spain’s update follows similar moves from the likes of the Netherlands, the U.K., Norway, Germany, and other prominent European states.

Ireland previously updated its travel information, citing similar reasons to Spain. The island nation also noted that visa and ESTA forms requiring travelers to declare their sex should reflect their biological sex at birth.

In March, Finland and Denmark also updated their guidance for transgender people visiting the U.S.

The United Kingdom also revised its guidance last month, warning citizens that failure to meet entry requirements could result in arrest or detention.

Similarly, Belgium and the Netherlands have taken steps to update their travel advisories for LGBTQ+ citizens.

Germany has also warned its citizens that possession of a visa or entry waiver does not guarantee entry.

Newsweek reported last month that neighboring Canada also made changes to its travel information for the U.S.

Canada’s government now mandates that citizens remaining in the U.S. for over 30 days register with U.S. authorities, cautioning that noncompliance could lead to fines or misdemeanor charges. This new requirement seems to reflect a broader U.S. initiative to more closely monitor foreign nationals living in the country.

“Canadians and other foreign nationals visiting the United States for periods longer than 30 days must be registered with the United States Government. Failure to comply with the registration requirement could result in penalties, fines, and misdemeanor prosecution,” the advisory stated.

Before this change, Canadians could stay in the U.S. for extended periods without needing to register or obtain a visa.

What People Are Saying

Spain’s travel information for the U.S. states: “The ESTA and U.S. visa application forms require travelers to state their gender. Recent measures adopted by the U.S. government require these forms to reflect the traveler’s biological sex at birth.”

What Happens Next

Whether more countries update their travel information for the U.S., seemingly in light of Trump administration policies, remains to be seen.
