Visa Info

If you are a national of a country that is a member of the United States Visa Waiver Program (VWP) then you do not need to apply for a visa to attend the symposium. If you are a national of any other country; however, you need to apply for a visa. You should do this as soon as possible as there is often a significant wait to receive a visitor visa.

Please visit the links shown to the right to check whether you are required to apply for a visa or not. If you have any doubts, please contact your local United States Consulate or Embassy. If you require a letter of invitation as part of your visa application, please email the IEEE BigDataSecurtiy 2020 organizers for more information.
