The Trump administration is barred from arresting and detaining legal refugees in Minnesota, a federal district court has ruled. Citizenship and Immigration Services (USCIS) — began an effort aimed at targeting and reexamining the legal status of some 5,600 refugees living in the state. On Jan. 18, a pseudonymous group of refugees sued over the policy in a petition for a writ of habeas corpus. § 1159 — gives DHS the power to subject refugees to mandatory detention. Still, despite the lack of such authority, the complaint notes that several legal refugees have been detained under the new policy.
