The Customs and Border Protection (CBP) is a federal agency of the United States Department of Homeland Security. Its primary role is to safeguard the nation's borders while facilitating lawful international trade and travel. CBP officers inspect goods and people entering the U.S. to prevent illegal activities, such as smuggling and human trafficking. CBP also plays a vital role in enforcing immigration laws and protecting agricultural resources. The agency works closely with other federal, state, and local law enforcement agencies to ensure national security and promote safe and efficient border operations.
