The U.S. Department of State (DOS) issues a Travel Warning when it identifies a chronic and sustained threat to U.S. citizens in a given country. Sometimes it warns against all travel there; sometimes it simply informs people of the risk. Travel Alerts usually address problems of finite duration, such as elections, public demonstrations, or hurricanes. The DOS also issues Security Messages and Emergency Messages, depending on the situation. To get updates for a particular trip, sign up for the DOS’s Smart Traveler Enrollment Program (STEP) at step.state.gov.
