I believe you can't bring funds, money has to be transfered from another country, bank to bank, then your bank will give you a letter to take to immigration, confirming funds were transfered from abroad.
apply in your own country, for a 3 month retirement visa, arrive day one, day 2 go and register your address at immigration, get stamp in passport, same day go to bank with letter from immigration, transfer funds. After funds in the bank for 3 months, go back to immigration, get 1 year retirement visa, cost. 1, 900 bht. simple.
or go to an agent and get it for 40,000 bht, maybe more next year.
I've live here long enough to know when I see a ten year old on a scooter with 2 or 3 of his or her mates on the back, they don't have a licence or tax or insurance.
car drivers are the same, they have no idea of the rules of the road.
yeah that's the problem where you are, police see you as an ATM, I live up north in Nan, police are great here, you never see them unless there's an accident. I've been told to slow down a couple of times with hand gestures, but that's it..
if you have the 800k don't bother with an agent. do it yourself for 1,900 bht. if you dont have the money then use an agent, but allways remember it's an illegal Visa. but safe enough as long as the government don't investigate the agent that stamped yours.
