He distinctly said "in most cases you can't work", and doesn't everyone know you don't (usually) come to Thailand to work? He was also up front admitting it's "a little more tricky" trying to stay permanently. But alas, it IS doable.
I went to an agent, saved me countless headaches and lots of time. Yeah, it was expensive, there's always going to be pushback from those who say "do it yourself", but I have no regrets.
