Overview
- Outgoing minister Patricia Bullrich unveiled the Agency on Nov. 25 and handed operational leadership to Alejandra Monteoliva, who takes over the ministry on Dec. 10.
- The Migration Police will assume security at land crossings and airports, replacing Gendarmería at borders and the Airport Security Police at terminals.
- Personnel will be drawn from existing federal forces and retrained for specialized duties, with the Dirección Nacional de Migraciones already moved under Security.
- Decree 366/2025 previously created an auxiliary migration police framework obliging federal forces to support Migraciones, paving the way for the new structure.
- The reform is part of a broader reorganization that models elements on U.S. Homeland Security and an FBI‑style Federal Investigations Department, with funding for 2026 still pending and potential legislative steps ahead.
