Borders of the United States

The United States shares international land borders with two nations:

• The Canada – United States border to the north
• The Mexico – United States border to the south

The Russia – United States maritime boundary was defined by a disputed agreement covering the Bering Sea, Bering Strait, and Arctic Ocean.

The Third Border Initiative is an area of foreign policy concerning the Caribbean Sea border between the United States and the Caribbean region.

Insular areas are in a separate customs territory from the 50 States, the District of Columbia, and Puerto Rico (see Foreign trade of the United States).

Agencies

U.S. Customs and Border Protection is responsible for policing the borders and inspecting people and goods being imported.

The United States Coast Guard actively patrols the nation's extensive maritime borders.

The United States Armed Forces and state and local police may also become involved in border enforcement in certain circumstances.
