Wow! You're going to be a real asset to the country. Are there any other laws you're planning on breaking or will it just be the ones concerning immigration?
How do you plan on getting around the Thai rules? Just curious. I too am looking into retirement in Thailand and assume I should follow the law of the land.
I checked the Vancouver consulate site because I know I read it before my visit last November. It does say evidence of adequate finance (20,000 Bhat person) but not that it has to be in cash. I took the equivalent of 13,000 Bhat but was well covered with my bank card and credit cards. It would be helpful if they stated it has to be 20,000 cash. I noticed some the examples you sited do say cash but not all of them.
The strange thing is that on the plan I have to convert to if I leave, hospital stays are covered but not any medical services. And then our dental plan is a worldwide plan. So strange.
