Tried to do the Ranong - Mayanmar boder bounce today. Luckily before I got stamped out, the immigration officer told me I must make sure that I have the three requisites ready for when I return, else they won't allow me back.
1. Proof of paid accommodation for the entire stay
2. Proof of leaving Thailand within the 30 days
3. 20000THB in CASH, no bank books or statements or other currency's, MUST be Thai Baht, in Cash.
People with multiple entry visas in the queue in front of me was advised that even with a valid visa, they are not guaranteed entry if the officer feels otherwise.
It is just too much of how a specific officer feels than what the rules state.
It was too mich of a gamble to be stuck in war-torn mayanmar, will do a flight to Malaysia during the week
