Worldwide Caution
As part of the Department of State’s continuous efforts to provide U.S. citizens traveling abroad with information about safety and security events, we are updating the Worldwide Caution with information on the continuing threat of terrorist actions, political violence, and criminal activity against U.S. citizens and interests abroad. This replaces the Worldwide Caution dated September 9, 2016.
As terrorist attacks, political upheaval, and violence often take place without any warning, U.S. citizens are strongly encouraged to maintain a high level of vigilance and take appropriate steps to increase their security awareness when traveling. To better prepare for possible emergencies, U.S. citizens are encouraged to read Country Specific Information pages, Travel Warnings, and Travel Alerts on travel.state.gov before planning a trip.
Travelers are urged to enroll in the Smart Traveler Enrollment Program (STEP) to receive security messages and make it easier to locate you in an emergency. The Department uses these security messages to convey information about terrorist threats, security incidents, planned demonstrations, natural disasters, etc. In an emergency, please contact the nearest U.S. Embassy or Consulate or call the following numbers: 1-888-407-4747 (toll-free in the United States and Canada) or 1-202-501-4444 from other countries.
