Before embarking on an international travel destination, of whatever length, make sure to register with STEP: The U.S. Department of State Smart Traveler Enrollment Program.

Through STEP, you can receive emailed travel alerts and warnings, and when registered, the U.S. government can better assist you with overseas emergencies including contact of United States family members.

Traveling is more fun when you are safe and accounted for!
