Visa Information

Finland is a member of the European Union and part of the Schengen area.

Everyone entering Finland must have a valid identification document. For EU citizens traveling within the Schengen Area, EU countries and Switzerland, a photo identification complying with EU standards and allowing international travel will suffice. Please check what kind of ID is required by your airline carrier before travelling. Some airlines within Europe will only accept passport identification.

Visas are required by delegates travelling from the rest of the world. We would encourage all delegates to check the requirements for their originating country. Please contact the nearest Finnish Embassy for further information. You can also find more information on visa requirements for Finland at

Please note that every delegate must apply for their own visa.
