I have just obtained my Non O based on volunteering and will be flying from Singapore to Chiang Rai vía Bangkok this Saturday.
Will I still be required proof of accommodation, 20k baht and outbound flight?
If so, would a bus ticket out of Thailand suffice and how accurate does the exchange rate has to be to show the equivalent of 20k baht if I don’t actually want to exchange the money to baht beforehand?
