Tamaulipas on the U.S. border and Sinaloa, Colima, Michoacan and Guerrero on the Pacific coast have been put under the most unsafe places, mostly because they either host trafficking routes or have widespread drug-crop cultivation.
India has been ranked Level 2, i.e. the United States citizens are advised to "exercise increased caution" when they travel to India.
While India has been put under Level 2, Pakistan is Level 3 which means "Reconsider travel to Pakistan due to terrorism".
"Do not travel due to crime", it states. In the case of Los Cabos, the latest advisory notes that "turf battles between criminal groups have resulted in violent crime in areas frequented by USA citizens".
In Jalisco, a Level 3 state that is home to Guadalajara and the Puerto Vallarta resort, there are no stay restrictions on U.S. government employees.
Mexico has 31 states in all. The tourism secretariat did not immediately return a request for comment from Travel + Leisure. "The FCO advises against all but essential travel to the city of Srinagar and travel between the cities of Jammu and Srinagar on the Jammu-Srinagar national highway".
In Kingston, the State Department said violence and shootings occur regularly and prohibited travel to downtown Kingston, which it defined as the areas between Mountain View Avenue and Hagley Park Road and south of Half Way Tree and Old Hope Roads. They require a one-time waiver explaining why they need to go. These advisory levels are simply a tool for you to use, and could impact world travel in some pretty meaningful ways.
The no-travel states had mostly already lost much foreign tourism.
The advisories cite drug cartel activity and violent crime, and the Tamaulipas warning was very blunt.
The country in general may have suffered its deadliest year of murders in 2017, according to preliminary figures, the BBC reports. Over the past two years, battles between cartels vying for control of supply routes to the lucrative US drug market have sent murder rates soaring and put large swaths of the country outside the effective control of the Mexican government.
The U.S. also issued "exercise increased caution" advisory for its citizens travelling to India.
Though the government's cautions remain largely the same as they were under the previous system of travel warnings and alerts, the numerical approach is new.
