@Henry *******
the 65,000 is Immigration req + whatever savings brings you over 800,000.
Just renewed mine for the 21st time a week ago.
They would prefer 800k locked in bank, but that's foolish, I use the income method and bank provides docs and letter.
Always try to make it 70k, to overcome any exchange rate flux, and don't worry about sav'gs.
Banks are very familiar with documents, cost 200 baht.
