Greece is part of the Shengen treaty so European Union travelers from other countries members of the treaty do not need a passport. All Citizens of European Union countries have free access. A visa is not needed for visitors from USA, Canada, Australia and New Zealand staying of up to three months. Visitors from all other countries have to obtain a visa from the Greek Embassy or the Consulate in their residence country.
An invitation letter for the purpose of obtaining a travel visa or permission to attend the meeting will be handed out on request after successful registration and payment for the conference.
