Visa Information for Foreign Travelers
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 United States. This authorization can be obtained online through the Electronic System for Travel Authorization (ESTA), a free Internet application administered by the U.S. Department of Homeland security.
For additional information about the ESTA please visit http://www.cbp.gov/esta.
Travelers from countries not in the VWP are required to obtain a Visa upon entry into the United States. If you need a visa, please contact us AS SOON AS you submit your abstract (deadline is Jan. 15, 2010) at email@example.com to request an invitation letter.
