A little bit late, but the USA State Department is warning citizens not to travel to Venezuela. As of right now, on Friday morning Caracas time, I'm seeing reports of looting, disturbances and riots in cities from San Cristobal in Western Venezuela to Maturin in the eastern oil field region.
All U.S. direct-hire personnel and their families assigned to the U.S. Embassy in Caracas are subject to an embassy movement policy that limits their travel within Caracas and other parts of the country. These security measures may restrict the services the Embassy can provide. Country-wide shortages of food, water, medicine, electricity, and other basic goods have led to social unrest, including violence and looting. Security forces have arrested individuals, including U.S. citizens, and detained them for long periods with little or no evidence of a crime. The U.S. Embassy may not be notified of the detention of a U.S. citizen and consular access to detainees may be denied or severely delayed. The detained citizen may be denied access to proper medical care, clean water, and food. This replaces the Travel Warning issued July 15, 2016."
