Yes, alerts from the National Terrorism Advisory System (NTAS) apply only to the United States and its possessions. The Department of Homeland Security issues these alerts to communicate credible information about terrorist threats within the U.S. and its territories. For Americans overseas or traveling internationally, the Department of State provides security advisory information instead. This distinction ensures that the NTAS specifically addresses threats relevant to domestic safety and security within U.S. jurisdiction.
