The US State Department has issued an updated travel warning for Americans planning to visit Mexico, particularly with the World Cup set to commence this month. While Mexico is categorized as a Level 2 'exercise increased caution' area, several states have been flagged with higher warnings. Specifically, six states—Colima, Guerrero, Michoacan, Sinaloa, Tamaulipas, and Zacatecas—are marked as Level 4 'do not travel' due to significant concerns over violent crime and security risks. Additionally, seven states, including Baja California and Jalisco, fall under Level 3 'reconsider travel.' The advisory emphasizes ongoing issues such as homicide, kidnapping, and robbery, alongside potential terrorist threats. Americans are reminded that US government resources in Mexico are limited, particularly in high-risk areas. To ensure safety, travelers are advised to follow specific guidelines, including avoiding travel at night and using regulated taxi services. The World Cup will feature 13 matches in Mexico, starting with the opening match on June 11, where Mexico will face South Africa in cities like Mexico City, Monterrey, and Guadalajara.
