The US government provides travel advisories to warn its citizens about the safety and security circumstances in numerous places across the world. These recommendations are intended to assist travelers in making informed decisions and minimizing risks while abroad.

While many countries are typically safe to visit, the US Department of State advises exercising caution or avoiding travel altogether owing to a variety of concerns such as political instability, terrorism, and natural disasters.

Travel advisory levels are released by the U.S. State Department for over 200 countries worldwide. These levels are updated regularly depending on a range of risk factors, including health, terrorism, and civil unrest. Level 1 travel advisories advise taking standard precautions, while Level 4 advisories advise not going there.

As of October 23, over 10% of countries—21 in total—had a Level 4: “Do Not Travel” advice. The State Department states that in Level 4 countries, the United States government may have “very limited ability” to take action if travelers’ security or safety is in risk.
