@Dany *******
the equivalent of 500 THB on a direct access bank account just is a visa requirement, which means Thai autorities are allowed to check.
That is not fear mongering, legitimate DTV holders have nothing to fear at all from checks.
And even illegitimate DTV holders do not have much to fear, because chances getteing checked ar less than a percent, but that still is higher than the chance you will win Thai lottery.
