Following the creation of the Department of Homeland Security, U.S. Customs and Border Protection (CBP) became the United States’ first border control agency solely in charge of processing people and goods crossing U.S. borders and stopping anyone or anything prohibited from entering.
CBP, alongside USCIS and ICE, took on responsibilities previously held by Immigration Naturalization Services after that agency was disbanded on March 1, 2003. The new agencies’ responsibilities were specified in the Homeland Security Act of 2002, which was a direct response to the 9/11 terrorist attacks. The act increased immigration enforcement and created the immigration system that is still in place today.
While CBP obtained consolidated responsibilities relating to border security in 2003 that other organizations previously handled, border patrolling had existed since the 1900s when mounted immigration guards began policing the United States’ borders. In 1924, the Labor Appropriations Act formalized the Border Patrol and gave it authority over the areas between border inspection stations. Officers operated out of El Paso, Texas, but their duties spanned as far as California.

While the department’s initial focus was on the southern border, it shifted to the Canadian border during the 1930s as the government cracked down on liquor smuggling. In 1952, border agents gained authority to board transportation operations to search for undocumented immigrants. That’s also when undocumented immigrants traveling in the U.S began to be subject to arrest.
CBP is one of the largest law enforcement agencies in the world with more than 60,000 employees.
