The United States government has collected DNA samples from upwards of 133,000 migrant children and teenagers—including at least one 4-year-old—and uploaded their genetic data into a national criminal database used by local, state, and federal law enforcement, according to documents reviewed by WIRED. The records, quietly released by the US Customs and Border Protection earlier this year, offer the most detailed look to date at the scale of CBP’s controversial DNA collection program. They reveal for the first time just how deeply the government’s biometric surveillance reaches into the lives of migrant children, some of whom may still be learning to read or tie their shoes—yet whose DNA is now stored in a system originally built for convicted sex offenders and violent criminals.

Spanning from October 2020 through the end of 2024, the records show that CBP swabbed the cheeks of between 829,000 and 2.8 million people, with experts estimating that the true figure, excluding duplicates, is likely well over 1.5 million. That number includes as many as 133,539 children and teenagers. These figures mark a sweeping expansion of biometric surveillance—one that explicitly targets migrant populations, including children.

Under current rules, DNA is generally collected from anyone who is also fingerprinted. According to DHS policy, 14 is the minimum age at which fingerprinting becomes routine.

“Taking DNA from a 4-year old and adding it into CODIS flies in the face of any immigration purpose,” she says, adding, “That’s not immigration enforcement. That’s genetic surveillance.”
Multiple studies show no link between immigration and increased crime.
In 2024, Glaberson coauthored a report called “Raiding the Genome” that was the first to try to quantify DHS’s 2020 expansion of DNA collection. It found that if DHS continues to collect DNA at the rate the agency itself projects, one-third of the DNA profiles in CODIS by 2034 will have been taken by DHS, and seemingly without any real due process—the protections that are supposed to be in place before law enforcement compels a person to hand over their most sensitive information.
