(The Hill) — The United Kingdom updated its advice for travel to the United States on Thursday, warning of harsh consequences for British passport holders who violate U.S. immigration laws.
The notice comes just a day after Germany updated its travel advice after three of its citizens were detained trying to enter the U.S.
The U.K. foreign office confirmed earlier this month that it was providing support to a British national detained in the U.S. after reports circulated of a woman detained at the border, Reuters reported.
In its updated advice, the U.K. foreign office told citizens to “comply with all entry, visa and other conditions of entry.”
“The authorities in the U.S. set and enforce entry rules strictly,” the office said. “You may be liable to arrest or detention if you break the rules.”
According to archived versions of the U.K. website, guidance in early February only stated that U.S. authorities “set and enforce entry rules,” Reuters reported.
Germany this week said it was investigating the cases of three of its citizens being denied entry and placed in detention when they tried to enter through the U.S. southern border.
Germany then updated its advisory to warn that entry through the Electronic System for Travel Authorization, or a U.S. visa, was not guaranteed, and U.S. border control has the final say in allowing people into the country.
A Canadian woman also said she was detained by Immigration and Customs Enforcement recently, The New York Times reported.
The detainments are causing international concern among allied countries as the Trump administration vows to crack down on migration into the U.S.
