The State Department is reviewing the records of more than 55 million immigrants who hold valid U.S. visas, threatening to revoke protections if any violations are found deemed deportable by the Trump administration. This includes what Trump officials declare engaging in any form of “terrorist activity.” Earlier this week, the Trump administration said it would expand its rigorous screening and vetting of social media posts of immigrant visa applicants to search for so-called anti-American views and activity. References to “anti-Americanism” can be found in the Immigration and Nationality Act of 1952, which at the time of its enactment primarily focused on targeting suspected communists.
