14 Countries on the US State Department's 'Do Not Travel' List

The U.S. State Department's travel advisory system includes four levels—Level 1 being "exercise normal precautions;" Level 2 meaning "exercise increased caution;" Level 3 signifying Americans should "reconsider travel" and Level 4 meaning "do not travel." Heading into summer 2019, only 14 countries are currently under Level 4 status and effectively a no-go for Americans. Travelers should avoid these places entirely when planning their next trip. In the meantime, be sure to create an account with the Smart Traveler Enrollment Program (STEP) and provide the details of your trip to receive the latest travel advisors and alerts as soon as they're issued.
