Britain warns travellers heading to US they face possible detention after Trump's immigration crackdown sees tourists locked up and sparks slump in American tourism

Tourists planning trips to the US are being warned that they could be barred entry or detained as experts suggested a series of high-profile border arrests could see traveller numbers drop off significantly. Donald Trump's immigration crackdown has seen US border officials using more aggressive methods with holidaymakers and legal immigrants, with the Trump administration calling it 'enhanced vetting', according to the New York Times. A US Customs and Border police officer stands guard at the San Ysidro Port of Entry in 2020 Becky Burke, 28, was handcuffed and taken to a detention cell in Tacoma, Washington, on February 26 and is now back in the UK Their forecast came even before the most recent flurry of detentions, which could further discourage potential tourists. American Pie actress Jasmine Mooney was also detained by ICE for nearly two weeks 'The final decision on whether a person can enter the US lies with the U.S. border authorities,' a spokesperson for Germany's Foreign Office said.
