Why would I want to become a US citizen lol?
17 million baht is NOT worth a long term US visa.
3 million baht is still a lot and my point is that it should be the same as yanks coming here, who have to invest ZERO.
To be frank, the immigration requirements should be stricter in Thailand than the US as it is a much better country, IMHO, no risk of our kids being shot at school, for a start. Not to mention the obese culture.
