The priority mission of the Border Patrol is preventing terrorists and terrorists weapons, including weapons of mass destruction, from entering the United States. Undaunted by scorching desert heat or freezing northern winters, they work tirelessly as vigilant protectors of our Nation's borders.
While the Border Patrol has changed dramatically since its inception over 86 years ago, its primary mission remains unchanged: to detect and prevent the illegal entry of aliens into the United States. Together with other law enforcement officers, the Border Patrol helps maintain borders that work - facilitating the flow of legal immigration and goods while preventing the illegal trafficking of people and contraband.
The Border Patrol is specifically responsible for patrolling nearly 6,000 miles of Mexican and Canadian international land borders and over 2,000 miles of coastal waters surrounding the Florida Peninsula and the island of Puerto Rico. Agents work around the clock on assignments, in all types of terrain and weather conditions. Agents also work in many isolated communities throughout the United States. Source: Border Patrol Overview.
