International Visas

Visitors from select countries may be eligible to visit the U.S. without a visa through the Visitor Waiver Program if certain requirements are met (including applying for an ESTA authorization). These countries include Andorra, Australia, Austria, Belgium, Brunei, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, or United Kingdom.

Entry without a visa through the Visa Waiver Program from an eligible country requires an Electronic System for Travel Authorization (ESTA) application, which can be completed online and paid for with an eligible credit card. A printout of an approved ESTA document will be required to board your flight to the United States. Visitors who obtain a visa and all citizens of Canada (traveling with a Canadian passport) are not required to apply for ESTA. Information is at help.cbp.gov/app/answers/detail/a_id/1094 and help.cbp.gov/app/answers/detail/a_id/1194/.

Other international attendees who will be joining us in Denver will require a visa. At the time of registration, you may request a visa letter from the Organizing Committee.
