Visa Information for Conference Travel to the USA
This information is provided for your convenience and may change. The only authoritative sources of travel information come from U.S. government websites (see links elsewhere on this page). Conference organizers cannot assume responsibility for the outcome of your visa application.
Countries Participating in the Visa Waver Program (VWP)
There are 38 countries that participate in the VWP. If your passport country is on that list, and you plan to be in the US for less than 90 days (and you have a valid passport that meets US requirements) you do not need a visa. Visit the VWP web page to see if your country is on that list.
