For those planning to visit Greece and, by extension, the Schengen Area, a visa may be required depending on your country of origin. You can find the list of countries requiring or exempt from a visa on the official website of the Hellenic Republic Ministry of Foreign Affairs.
ERA Congresses & Events, the Professional Congress Organizer of the 2nd World Keratoconus Congress (WKC 2025) will be happy to provide a letter of invitation to participants who need it for their visa application process.
Please feel free to contact us if you require any assistance.
