Describe the role of Customs and Border Protection (CBP).

The role of Customs and Border Protection (CBP) encompasses a variety of functions, primarily focused on enforcing immigration laws and regulating trade. As the largest federal law enforcement agency within the Department of Homeland Security, CBP is tasked with safeguarding America's borders, which includes preventing illegal immigration and trafficking.

By enforcing immigration laws, CBP ensures that individuals crossing the border meet the necessary requirements for entry into the United States, while also monitoring trade to facilitate lawful commerce while preventing illicit activities. This dual responsibility is critical in maintaining national security and supporting economic interests.

In contrast, other options like providing legal advice on immigration matters, processing asylum claims at U.S. ports, and assisting visa applicants with their documentation fall outside the core responsibilities of CBP. Legal advice is typically provided by immigration attorneys or organizations specializing in immigration law. Asylum processes are generally handled by U.S. Citizenship and Immigration Services (USCIS), which specifically focuses on processing and adjudicating claims for asylum. Lastly, assistance with visa documentation is typically within the purview of the Department of State, which manages consulates and embassies abroad.
