rubbish people using the visa agent's doing that already especially the retirement visa. And even if you get a long visa you need to leave and do a border crossing
like me it's hard to get a visa only so many education visa you can get . Especially for people under the age of 50 . Some people do have money and invested in Thailand they don't need to work in Thailand
And that elite visa is a joke the price they are asking
If they introduced a visa that allowed people to stay in the country that was reasonable money and stop border crossing .
