If you need a travel visa, begin the visa application process now! You need to allow a minimum of 6 weeks processing time for the entire visa application process (from application for the invitation letter to receiving the visa). Advance travel planning and early visa application are important, since visa applications are subject to a greater degree of scrutiny than in the past. See links below for more information about Visa and passport requirements for travel to the Czech Republic.
Nationals of all Western European countries can visit the Czech Republic without a visa; US, Canadian, and Australian passport holders can stay up to 90 days without a visa. For additional details and specific visa requirements, please contact the Czech Embassy in your country.
PLEASE NOTE: Submit an invitation letter request by 1 February 2023
Requests for invitation letters for program participants received beyond this date may not have sufficient time to apply and receive the visa from the Embassy.
SPIE recommends that you secure your travel visa before registering for the conference as cancellations after the preregistration cutoff date may result in a cancellation fee.
