Immigration and Customs Enforcement (ICE) is taking advantage of DNA testing technology to identify migrants posing as families in order to gain entry to the United States at seven locations along the U.S./Mexico Southern border.
Although voluntary, documents released earlier this year suggest families are more likely to be separated if they refuse.
