it's not the organisation that is telling me, and it's an organisation I have used many times before in Europe where you don't require a work permit to do voluntary work...
You don't need the 800k if you use an agent or find a 'tame/bent' immigration officer (there are plenty running scams to get round the 800k requirements) Thailand is very corrupt and a cash bung solves many 'difficulties' but I didn't tell you that 🤣🤣🤣
