A new Department of Homeland Security task force is using data analytic tools to scour the social media histories of the estimated 1.5 million foreign students studying in the United States for potential grounds to revoke their visas. The move is being criticized by immigration-law and free-speech experts, arguing the government could use it to target political speech it dislikes.
Among the speech being looked out for by the new task force is what the agency deems to be antisemitic activity on social media and "physical harassment of Jewish individuals" as grounds to revoke or deny immigration benefits.
