The Laken Riley Act (LRA) was signed into law by President Trump on January 29, 2025. It amends the Immigration and Nationality Act (INA) by expanding mandatory detention of certain inadmissible noncitizens who are merely arrested or charged with certain offenses. This practice advisory addresses the question of whether the provisions of the LRA that seek to vastly increase the number of people subject to mandatory immigration detention would be triggered by children engaging in acts of juvenile delinquency. In the advisory, we argue that the answer is no, in alignment with longstanding precedent in immigration law that treats acts of juvenile delinquency as distinct from adult criminal acts. However, given that this is a new law with unclear drafting, we also provide tips for juvenile defense attorneys to help clients avoid charges that could implicate the mandatory detention provision of the LRA.
