What does HSI's authority in border search primarily involve?

HSI's authority in border search primarily involves conducting searches related to national security. This authority stems from the need to protect the country's borders from threats such as terrorism, trafficking, and other criminal activities that could violate the nation's security.

When HSI conducts border searches, they are often looking for items or individuals that could pose a risk to national security. This includes the interception of contraband, illegal immigration, and identifying potential threats before they enter the interior of the country. The framework within which HSI operates allows for these border searches to be conducted as a preventive measure to maintain safety and security.

While criminal and financial investigations may play a role in broader agency functions, they are not the primary focus of border search authority. Furthermore, compliance with international law is always an aspect of law enforcement, but it does not specifically define HSI's authority in the context of border searches. Ensuring national security through relevant searches is the key aspect attributed to HSI's border search authority.
