Which agency is responsible for enforcing U.S. trade and immigration laws?

Customs and Border Protection (CBP) is the agency responsible for enforcing U.S. trade and immigration laws. This agency plays a crucial role in protecting the U.S. borders and facilitating lawful trade and travel. CBP oversees the inspection of goods and individuals entering the country, ensuring compliance with all legal regulations and safeguarding national security.

The agency's duties include collecting tariffs and duties on imported goods, preventing illegal smuggling of items, and monitoring immigration to ensure that individuals who enter the U.S. adhere to the established immigration laws. As part of its mission, CBP employs various strategies and technologies to effectively manage the flow of goods and people, ensuring the safety and security of the nation.

The other agencies mentioned have distinct responsibilities: the Federal Aviation Administration regulates civil aviation, the Transportation Security Administration focuses on airport and transportation security, while the U.S. Coast Guard primarily conducts maritime safety and law enforcement missions over navigable waters and ports. Each agency plays an essential role in the broader framework of national security and transportation but does not have the same scope of responsibility regarding trade and immigration laws as Customs and Border Protection does.
