It is the delegate’s responsibility to investigate the visa requirements for entry to Czech Republic and to apply for a visa, if necessary. Delegates who require an entry visa must allow sufficient time for the application procedure.
Visitors from non-EU countries must possess a passport valid for at least three months after the planned departure from the Czech Republic. Please note that the visa application process can take up to 2 months or more. Therefore, the participants requiring visa should apply immediately to the consular office or embassy of the Czech Republic in their home country in order to avoid any inconvenience. See the list of countries whose citizens require a Visa here.
