The ONLY agency present at ALL ports of entry is which agency?

• A. US Customs and Border Protection
• B. CDC
• C. APHIS
• D. USFWS

Answer: (A)

The key idea is identifying the agency that is stationed at every point where people and goods enter the country. US Customs and Border Protection is the front-line agency responsible for screening and inspecting all travelers and cargo at every port of entry—air, sea, and land. That universal presence means CBP is the only agency guaranteed to be there at all entry points. Other agencies have important roles—such as handling public health concerns, agricultural imports, or wildlife concerns—but their inspectors operate at selected ports or under specific circumstances, not at every single port. So, the agency with coverage at all ports is US Customs and Border Protection.
