The answer is pretty simple.
As the United States prepares to host the Winter Olympics in South Korea, the country has issued a travel advisory for visitors who plan to travel outside of the United State and to the International Olympic Committee’s “Olympic City” zone in Brazil.

The country has also put out a call for visitors to watch for police patrols and the potential for more demonstrations.
