Operation Metro Surge is a large, interior immigration‑enforcement deployment launched in December 2025 in Minnesota to identify, arrest and remove noncitizens subject to removal. DHS has publicly described it as a multi‑component surge led by Immigration and Customs Enforcement (ICE) — including ICE’s Enforcement and Removal Operations (ERO) and Homeland Security Investigations (HSI) — with support from Customs and Border Protection (CBP)/Border Patrol and other DHS law‑enforcement resources.
