Tourists from Turkey prepare their sailboat in Vathy village, in Samos island on July 24, 2026. Introduced in April 2024, the visa-on-arrival scheme, known in Turkey as the "door visa" (kap vizesi), initially covered 10 Greek islands before being renewed and expanded to 12 last year. The list of islands -- all near the Turkish coast -- include Rhodes, Chios and Kos. (Photo by Sakis Mitrolidis / AFP via Getty Images)
