Why are European countries warning European travelers to be careful traveling to the United States?

A Canadian woman who was detained for nearly two weeks by immigration officials in the U.S. is speaking out about her experience in an extensive account for The Guardian, titled “It felt like I had been kidnapped.”

She spent 12 days in detention, under what her supporters described as “inhumane conditions,” with no clear explanation as to why U.S. Customs and Border Protection had arrested her. “We treat cattle better than this in Canada,” her mother, Alexis Eagles, said during her incarceration.

Jasmine Mooney, a 35-year-old business consultant from Vancouver, was detained by U.S. immigration officials while attempting to cross the border with a job offer and visa paperwork in hand.

Why cant I sleep? When I'm about to fall asleep, I get excited that im about to sleep, causing me to wake up again. It repeats till my sleepiness is gone. I tried taking melatonin and not using my phone, but I end upawake for hours.

Lennon Tyler and her German fiancé often took road trips to Mexico when he vacationed in the United States since it was only a day’s drive from her home in Las Vegas, one of the perks of their long-distance relationship.

there have been other incidents of tourists like Sielaff being stopped at U.S. border crossings and held for weeks at U.S. immigration detention facilities before being allowed to fly home at their own expense.

They include another German tourist who was stopped at the Tijuana crossing on Jan. 25. Jessica Brösche spent over six weeks locked up, including over a week in solitary confinement, a friend said.

A kid threw a stone at my car. I confronted his mom (who was nearby). She said, "You can't prove it was my son." How should I have reacted?

But things went terribly wrong when they drove back from Tijuana last month.

U.S. border agents handcuffed Tyler, a U.S. citizen, and chained her to a bench, while her fiancé, Lucas Sielaff, was accused of violating the rules of his 90-day U.S. tourist permit, the couple said. Authorities later handcuffed and shackled Sielaff and sent him to a crowded U.S. immigration detention center. He spent 16 days locked up before being allowed to fly home to Germany.
