Legal Definitions - Customs and Border Protection (CBP)

The Customs and Border Protection, also known as CBP, is a law enforcement agency that operates under the Department of Homeland Security. Its main responsibility is to prevent illegal entry into the United States. CBP also ensures that harmful or illegal items are not brought into the country.

CBP meets travelers and returning residents at airports and border posts, checking their visas and admission documents. They decide whether individuals are allowed into the United States or not. If someone is not allowed, CBP orders them to return home.

CBP also regulates international trade, collects import duties, and enforces customs, trade, and immigrationregulations. They provide security and facilitation operations at 328 ports of entry throughout the country.

For example, if someone tries to bring illegal drugs into the United States, CBP will stop them at the border and confiscate the drugs. If someone does not have the proper visa or admission documents, CBP will not allow them to enter the country. CBP also collects import duties on goods that are brought into the country, such as electronics or clothing.
