Intelligence and Vetting

• Biometric Screening: Expanding the use of advanced fingerprint, facial recognition, and database checks at all ports of entry. [1, 2]
• Watchlist Integration: Improving real-time data sharing between U.S. Customs and Border Protection, the Federal Bureau of Investigation, and international partners to flag high-risk individuals early.
• Investigative Tracking: Deploying specialized units to trace and dismantle illicit smuggling networks that move individuals from countries of concern. [1]

Border Operations and Enforcement

• Surveillance Technology: Utilizing mobile towers, non-intrusive inspection scanners, and aerial drones to monitor remote areas.
• Interagency Coordination: Deploying federal law enforcement and security personnel to high-risk sectors to ensure rapid response and thorough screening capabilities.
