For many countries a visa is required for entry into the United States. We urge all participants to apply for visa as early as possible.
For help with visa, or to request a letter of invitation, please contact Carol Soren, Conference Secretary (e-mail: firstname.lastname@example.org) or Local Organizing Commettee.
Change to the Visa Waiver Program: Beginning January 12, 2009, all nationals and citizens of Visa Waiver Program countries will be required by law to obtain a travel authorization prior to initiating travel to the United States under the VWP. This authorization may be obtained online through the Electronic System for Travel Authorization (ESTA), a free Internet application administered by the Department of Homeland Security (DHS) through a U.S. government Web site: https://esta.cbp.dhs.gov.
