Visa Information

Beginning January 12, 2009, all nationals and citizens of Visa Waiver Program (VWP) countries who plan to travel to the U.S. for temporary business or pleasure for 90 days or less will be required by law to obtain travel authorization prior to initiating travel to the US. This authorization can be obtained online through the Electronic System for Travel Authorization (ESTA), a free Internet application administered by the US Department of Homeland security. For additional information about the ESTA visit https://www.cbp.gov/esta. Travelers from countries not in the VWP are still required to obtain a Visa upon entry in the US and can download an individual acceptance letter as described below.
