The Trump administration on Tuesday tightened immigration vetting, directing U.S. Citizenship and Immigration Services officers to treat endorsement or promotion of “anti-American” or antisemitic ideologies as a heavily negative factor when adjudicating applications for citizenship, permanent residence and other immigration benefits. The policy update—effective immediately and incorporated into USCIS’s Policy Manual—extends to pending and future cases, including parole and EB-5 investor visas. Officers are instructed to scour public records and social-media posts for hostile content. Applicants must still meet all statutory eligibility requirements but now bear a higher burden to show “good moral character,” a standard the agency broadened in an earlier August memo to weigh positive contributions such as community service, steady employment and tax compliance. “America’s benefits should not be given to those who despise the country,” USCIS spokesman Matthew Tragesser said, adding that immigration privileges must align with national security and the administration’s America First agenda. The move follows a series of measures aimed at tightening discretion over immigration benefits and mirrors wider U.S. requirements for foreign visa seekers to share social-media histories. Nigeria’s Foreign Ministry said it will adopt identical disclosure rules for American travelers in response to Washington’s mandate for Nigerians.
