Americans are being advised not to travel to the states of Colima, Guerrero, Michoacán, Sinaloa and Tamaulipas due to crime.

In Guerrero state, armed groups operate independently of the government in many areas and frequently maintain roadblocks and may use violence toward travelers, according to the U.S. government. Criminal organizations are operating in Sinaloa state, where violent crime is widespread. In Tamaulipas state, organized crime activity, including gun battles, murder, armed robbery, carjacking, kidnapping, has led to disappearances, extortion and sexual assault.

If Americans travel to Mexico, they are advised to keep their traveling companions and family back home informed of their travel plans, and if separated from their travel group, to send a GPS location. If taking a taxi alone, text a photo of the taxi number and license plate to a friend or family member.
