The U.S. Border Patrol seeks to prevent illegal entry into the United States along the 8,000 miles of land and water boundaries of the United States between ports-of-entry.
The southwest border covers four states: California, Arizona, New Mexico, and Texas.
The voluntary returns program allows aliens to enter an agreement to leave the United States of their own volition to avoid further consequences.
