A French scientist was denied US entry, reportedly due to opinions on Trump's research policy, sparking concern from the French government.
PARIS (Reuters) - A French scientist has been denied entry into the U.S., apparently because the scientist had expressed a personal opinion on the Trump administration's research policy, the French Education Ministry said on Thursday.
"I learned with concern that a French researcher on assignment for the French National Center for Scientific Research (CNRS) who was traveling to a conference near Houston was denied entry to the United States before being expelled," Minister for Higher Education and Research Philippe Baptiste said in a statement to AFP.
The measure was apparently taken because the scientist had expressed a personal opinion on the Trump administration's research policy, he added, but did not elaborate.
An Education Ministry spokesperson confirmed the reports by AFP and Le Monde over a scientist being denied entry, without giving details.
When contacted, the U.S. Embassy in Paris referred to the U.S. Customs and Border Protection agency.
U.S. customs did not immediately reply to an emailed request for comment.
President Donald Trump's administration has taken various steps to cut or freeze federal funding for universities, medical centres and other research institutions since he took office in January.
On border matters, Trump has announced a number of immigration-related executive orders that focus on stricter border policy, tighter visa vetting procedures and a crackdown on undocumented migrants in the United States.
Germany this week updated its travel advisory for the U.S. to emphasise that a visa or entry waiver does not guarantee entry for its citizens after several Germans were detained at the border recently, a foreign ministry spokesperson said.
In recent weeks Britain has also revised its advice for citizens travelling to the U.S., to include a warning that anyone found breaking its entry rules could face arrest or detention.
