Data

The Terrorist Screening Dataset (TSDS) – also known as the “watchlist” – is the U.S. government’s database that contains sensitive information on terrorist identities. The TSDS originated as the consolidated terrorist watchlist to house information on known or suspected terrorists (KSTs) but has evolved over the last decade to include additional individuals who represent a potential threat to the United States, including known affiliates of watchlisted individuals.

Encounters of watchlisted individuals at our borders are very uncommon, underscoring the critical work CBP Agents and Officers carry out every day on the frontlines. DHS works tirelessly to secure our borders through a combination of highly trained personnel, ground and aerial monitoring systems, and robust intelligence and information sharing networks.

TSDS watchlisted non-citizens encountered by the CBP Office of Field Operations at land ports of entry prior to entry into the United States may be denied admission to our country upon presentation, barring justification for their arrest under CBP policy. TSDS watchlisted individuals encountered by the U.S. Border Patrol (USBP) after entering the country without inspection may be detained and removed, to the extent possible under CBP policy, or turned over to another government agency for subsequent detention or law enforcement action, as appropriate.

*POE totals may include multiple encounters of the same individual.
