Britain has in recent weeks revised its advice for citizens travelling to the United States to include a warning that anyone found breaking its entry rules could face arrest or detention.

Axar.az reports citing Reuters, current British travel advice for the United States published online by Britain’s foreign office stated:

“You should comply with all entry, visa and other conditions of entry. The authorities in the US set and enforce entry rules strictly. You may be liable to arrest or detention if you break the rules.”

Archived versions of the same website showed that at the beginning of February, the guidance had only stated: “The authorities in the US set and enforce entry rules.”
