Establishes provisions to provide for legal representation for undocumented minors in immigration matters

HB 3159 requires Missouri's Department of Social Services to provide free legal counsel to undocumented minors under 18 in immigration matters. It directly affects immigrant children identified as unaccompanied or without guardians, covering both state court proceedings and federal immigration cases like asylum or T-Visa applications. Key provisions mandate counsel be appointed when a child is designated as an "immigrant child" (defined as under 18 without lawful status or parental support), and specify that legal services must be provided by qualified nonprofits or public defenders with experience in immigration cases. The bill ensures ongoing representation until case resolution, even if the child turns 18 during proceedings.
