The U.S. Customs and Border Protection was established on March 1, 2003 in the Directorate for Border and Transportation Security, Department of Homeland Security.
U.S. Customs and Border Protection is responsible for guarding nearly 7,000 miles of land border the United States shares with Canada and Mexico and 2,000 miles of coastal waters surrounding the Florida peninsula and off the coast of Southern California. The agency also protects 95,000 miles of maritime border in partnership with the United States Coast Guard.
CBP’s priority mission is to prevent terrorists and terrorist weapons from entering the United States and ensuring the security of our nation at America's borders and ports of entry. We must maintain this line of defense while allowing legitimate travel and trade that is vital to our economy and way of life.
CBP is responsible for apprehending individuals attempting to enter the United States illegally; stemming the flow of illegal drugs and other contraband; protecting our agricultural and economic interests from harmful pests and diseases; protecting American businesses from theft of their intellectual property; and regulating and facilitating international trade, collecting import duties, and enforcing U.S. trade laws.
