If you go to Koh Samui they give you the full extension in a couple hours. I just went this morning. I checked in to a hostel for a couple days, Monkey Samui hostel, and they let immigration know you are staying there. I didnt get Under Consideration. Just the full extension. Also if your Koh Tao place lets immigration know you are staying there you wont have to actually stay anywhere on Samui. A lot of people from Koh Phangan do that
I arrived in thailand March 2020 with ‘Visa on Arrival’. Since then I have done one extension, then amnesty, then 60 day extensions. I am just getting another 60 day extension. I never changed my visa to education or volunteer, just extensions on the original ‘visa on arrival’
yes that is what I have been worried about and researching a lot. If I fly to suratthani or samui and go straight to phangan do you know if i will have to quarantine?
