right, so this post has zero actual information about anything, it's purely your "common sense", which is already contradicted by reports from people who have got the visa.
you pay up front and don't get it back if not approved but it does seem consulates are going back to people to ask for further documents where they want them, not just rejecting the application.
you would "think" but how is what you "think" actually useful information? What's actually useful is reports of people who got one, and there are reports from people who got it showing only very short need to be here. There's no indication of any need to prove you need to be here for five years, every indication is the opposite.
someone posted who got one with a single once off medical appointment so I don't think what you're saying is actually right, people ARE getting them without having to prove they need to be here for 5 years.
it's 500,000 THB or $16,000, if you're showing a statement in USD, it's $16k. Hopefully they will show you some leniency but that's the requirement from that embassy.
they have talked about easing the requirements for retirees as well, that is meant to be coming in the next few months. Possibly a reduction of the O-A insurance requirement.
this depends on the consulate, no? As the MFA says a sponsorship letter is a possibility. I know some consulates aren't, and aren't accepting payslips either, but it's a theoretical option for the visa.
that site is not official anything, it's just a site designed to capture search traffic. It doesn't say anything about it being limited to two entries within the five years anyway.
The government have been clear at every point it is a multiple-entry visa. What you describe is a double-entry visa, they used have these but this is not that.
