What is the primary focus of Customs and Border Protection?

The primary focus of Customs and Border Protection (CBP) is to facilitate international trade and immigration. This agency plays a crucial role in securing the borders of the United States while ensuring the efficient flow of goods and people across these borders. Its responsibilities include preventing illegal immigration and smuggling, collecting duties and tariffs on imported goods, and enforcing U.S. regulations regarding trade. CBP balances the need for security with the need for economic efficiency, helping to manage and support U.S. trade interests while protecting the nation from potential threats.

In the context of the other options, while regulating U.S. commercial space transportation, maintaining the national airspace systems, and overseeing public health initiatives are important government functions, they fall under different agencies and areas of focus beyond the specific mandate of Customs and Border Protection. CBP's operations are centered on customs enforcement and border security, making the facilitation of international trade and immigration its defining mission.
