Hi all, sorry for the stupid question. When is the earliest you can apply for extension with the 30 day tourist stamp please? And am i right in saying that you can apply for this extension online? Or i’d have to show up in person? Thanks so much
TLDR : Answer Summary
You can apply for an extension of your 30-day tourist stamp in Thailand when you have 30 days or less on your visa. However, in Koh Samui and Pattaya, applications can only be made when there is one week or less remaining. The application must be done in person at an immigration office, as there is no fully online extension process available, although some parts of the process may be facilitated online.
