The Department of State has issued this Travel Warning to inform U.S. citizens about the security situation in Venezuela. Tens of thousands of U.S. citizens safely visit Venezuela each year for study, tourism, business, and volunteer work. However, violent crime in Venezuela is pervasive, both in the capital, Caracas, and in the interior. Moreover, since February 2014, frequent demonstrations have taken place throughout Venezuela, and may pose a security risk. This Travel Warning updates the Travel Warning issued on November 22, 2013, to include information on the ongoing demonstrations and additions to the movement policy for U.S. Embassy personnel and their families.
