Please check to see whether a visa is required for you to enter Estonia
for the 2020 WDCC. The following link lists countries who do not need a
Visa to visit Estonia: https://vm.ee/en/who-does-not-need-visa-visit-estonia
If your country is not on the list it means that you need a visa, please
follow this link to apply for a visa to visit Estonia (Schengen Area): https://vm.ee/en/applying-visa-schengen-area
If you need a visa to visit Estonia, please apply as soon as possible
because for citizens of some countries it can take a long time. We have had participants (especially from African countries) who have had difficulties competing in ICSD competitions in the past because not enough time was allowed to organise their visas.
