Hello,i plan to travel to thailand for 85 days.if i get the 60 days visa from the embassy in Athens ,may i buy the extension for the other 30 fays in koh samui immigration or i have to go out of the country and come back??do hou suggest a better way?? Thank you
TLDR : Answer Summary
You can obtain a 60-day tourist visa from the embassy in Athens and then apply for a 30-day extension at the Koh Samui immigration office before the end of your initial visa period. It's important to note that extensions can only be applied for during the last week of your current visa. This option is convenient and allows you to stay in Thailand for a total of 90 days without having to leave the country.
