Check announcements from the Greek Ministry of Foreign Affairs and the competent Greek consular authority in Türkiye. Look at both the publication date and the travel period covered by the notice. An older official announcement remaining online does not establish that the same arrangement operates in a later season. Alongside the island list, check designated ports, eligible passport categories, permitted stay conditions and the required submission channel. If the announcement does not address your circumstances, request clarification from the relevant consular authority. Ferry operators can explain sailing and document-handling logistics, but those operational details should be distinguished from the scheme’s official legal scope.
