agree. I’m willing to bet he couldn’t stump up the 800k. The 65k a month is of course an option but I’ve seen enough “but the bank book has to state this or state that or have blue stripes and lime green polka dots and the moon must be waxing” to think 800k is the safest and surest. Hard to question and no special statements in the bank book
If you can’t afford to have 800k then maybe you should consider living elsewhere
Here’s a link but as with all things Thai check with the embassy you will be filing with or the Thai immigration office you use because things can change on a dime
