- Synchronize policy across multiple U.S. government departments (State, Treasury, Homeland Security, Commerce, etc.).
- make easier real‑time communication with Mexican counterparts, including the Secretaría de Relaciones Exteriores (SRE) and various ministries.
- Coordinate cross‑border programs ranging from trade facilitation and migration management to public health and environmental protection.

- Mid‑20th Century: The rise of NAFTA (1994) amplified economic interdependence, prompting the U.S. to formalize its Mexico‑focused diplomatic infrastructure.
- 2011: The Office of Mexican Affairs was officially inaugurated within the State Department’s Bureau of Western Hemisphere Affairs (WHA), consolidating expertise on Mexico under one roof.
