Visa Waiver Program for International Travelers

International travelers who are seeking to travel to the United States under the Visa Waiver Program are now subject to enhanced security requirements. All eligible travelers who wish to travel under the Visa Waiver Program must apply for authorization. Go to the Electronic System for Travel Authorization Web Site at https://esta.cbp.dhs.gov. In addition, please be aware that certain travel documents must contain a “biometric identifier” in order to gain entry into the United States.

When applying for a visa, the United States Consulate will require a letter of invitation from ISSF 2012. Therefore, we kindly ask that you email your request for us to send you the official letter of invitation with the text that the letter should contain. The official letter of invitation should be requested several months in advance of the May 2012 conference, as it may take up to 6 months to get the visa processed. If you intend to submit an abstract to the conference, we encourage you to submit the abstract prior to requesting the official letter of invitation.
