French Researcher Deported from U.S. Over Criticism of Trump Administration Policies

The French government has condemned the deportation, citing concerns over academic freedom and international cooperation.

A French researcher associated with the CNRS was denied entry to the U.S. on March 9, 2025, following a random customs check at a Houston airport.
U.S. authorities reportedly based the deportation on messages on the researcher’s electronic devices criticizing Trump administration research policies.
The French Ministry of Higher Education and Research has emphasized the importance of academic freedom and expressed regret over the incident.
The French Ministry of Foreign Affairs acknowledged U.S. sovereignty over immigration decisions but reiterated its commitment to freedom of expression and scientific collaboration.
The incident has reignited broader concerns about the Trump administration's perceived hostility toward the scientific community, including budget cuts and restrictions on research topics.
