U.S. Immigration Agencies Expand Genetic Surveillance, Raising Ethical Concerns
U.S. immigration agencies have significantly expanded their use of DNA testing, moving beyond verifying family relationships to collecting and indexing genetic information from immigrant communities, including an estimated 2,000 U.S. citizens. This genetic data is now being deposited into the FBI’s Combined DNA Index System (CODIS) database, which was originally established for solving violent crimes. As of December 2025, the number of samples indexed in CODIS from this expanded collection exceeded 3.3 million. This development was highlighted in an ELSI Friday Forum, which discussed the current state of DNA testing within immigrant communities in the U.S. and the ethical, legal, and social implications of the government’s increased genetic surveillance capabilities for both immigrants and citizens. The forum featured discussions led by Christi Guerrini, JD, MPH, and presenters Stevie Glaberson, JD, LLM, and Medha Makhlouf, JD.
