United Kingdom

The United Kingdom warns its citizens about new US immigration requirements. The country has updated its advice on travel to the United States, strongly urging Britons to comply with all entry and visa requirements. The new recommendations also highlight the high risks of violating immigration laws, emphasizing that this can lead to detention and arrest. Previously, it was only indicated that the United States sets entry rules, but now a specific warning about possible detentions has been added.

Germany

German authorities have stressed that having a visa or ESTA authorization does not guarantee automatic entry to the United States. The final decision is made by the border service, so travelers are advised to carry documents confirming the purpose of the trip and financial capacity.

Overstaying a visa, previous criminal records, or incorrect travel information can lead to arrest, detention, or deportation.

Canada

Canada advises travelers to carefully familiarize themselves with US immigration requirements. The country's government also urges its citizens to carefully study US immigration regulations before traveling.

The updated guidance emphasizes that each country has the right to determine its own entry regulations, and the Canadian government cannot help if travelers are denied entry to the United States.

The decision to travel to the United States is the responsibility of travelers themselves.

Important! The US has also introduced a new requirement: citizens and foreign residents who are in the US for more than 30 days must register in a special system. Failure to comply with this rule is subject to fines and other sanctions.

Difficulties in traveling to the US with a gender marker “X”

Finland and Denmark have drawn attention to the possible difficulties for travelers whose passports indicate a gender marker “X”, which does not correspond to the sex indicated at birth. In such cases, it is recommended to consult the US embassy in advance.

Several countries, including Australia, Canada, Germany, India, Malta, the Netherlands, New Zealand, Pakistan, the USA, Argentina, Iceland and others, have introduced an “X” marker in their passports instead of the traditional “M” (male) and “F” (female) to designate non-binary, intersex or other individuals. Depending on the country, this token may require medical or legal verification or be available at the citizen’s request.

Complicating US immigration law for expats

The US government has reiterated that visa holders are subject to ongoing scrutiny even after they are issued a visa. Even lawful permanent residents (green card holders) are not exempt from increased scrutiny. Senator J.D. Vance recently emphasized in an interview with Fox News that having a green card does not guarantee the right to remain in the US indefinitely.

There are reports that Customs and Border Protection (CBP) officers are specifically pursuing these travelers upon their return to the US. The Times of India reports that officers are pressuring individuals to sign Form I-407, which is effectively a waiver of their right to permanent residence. Those who resist are threatened with detention or deportation. Therefore, green card holders who spend a lot of time abroad should be especially careful about their travels.
