The Border Patrol is an office of U.S. Customs and Border Protection, the agency within the Department of Homeland Security charged with the protection of our nation's borders. As a Border Patrol Agent, your primary focus would be to work in tandem with your U.S. Customs and Border Protection partners to prevent terrorists and terrorist weapons from entering the United States. Border Patrol Agents also detect and prevent the smuggling and unlawful entry of undocumented aliens into the United States, and apprehend those people found to be in violation of the immigration laws.  Also, due to the increase in drug smuggling operations, the Border Patrol is the primary drug-interdicting agency along the land border between the ports of entry.
