Federal Advisories Flag Risk for Travelers in Iran, Mexico

The U.S. government ranks travel risk on a scale of 1 to 4, and Level 4 means do not travel. As of October 2026, Iran carries that Level 4 warning. Parts of Mexico, including specific tourist areas, also sit at Level 4.

The State Department maintains a website listing advisories for countries worldwide. The agency assigns each country a numerical risk level. The highest level, 4, instructs travelers to avoid the destination because risks outweigh benefits. Iran is on the list. Specific regions of Mexico, including tourist areas, are on the list.

The advisory for Iran comes as the United States has evacuated nonessential personnel from the region over concerns about the Middle East. The situation in Ukraine continues as Ukraine fights Russia, a conflict that affects energy costs and oil prices. The source material described the situation in Iran as more severe than the situation in Ukraine.

Travel to Canada and Mexico carries its own concerns. The Canadian government is in a public dispute with President Trump, and some Canadians no longer welcome American visitors. Drug cartels in Mexico have increased activity against the Mexican government since President Trump closed the border. Incidents have occurred even at well-known resorts.

Within the United States, many people have moved to Idaho from California and Washington State, citing crime and safety concerns. The source material advised against visiting Los Angeles and Seattle in the current environment.

Idahoans who work for international companies such as Simplot and Micron may travel abroad for work. The State Department advises travelers to check whether a destination appears on the Level 4 list before booking a trip.
