A class action lawsuit filed by six detained noncitizens challenges a Trump-Vance administration policy that blocks detained immigrants from completing biometric collection while allowing the government to deny their pending immigration applications for failing to complete that same requirement. The lawsuit, filed in U.S. District Court for the District of Columbia, argues the policy creates an unlawful procedural trap that violates federal immigration law, the Administrative Procedure Act, and Fifth Amendment due process protections by making mandatory compliance impossible for detained applicants.
