What are the requirements for maintaining funds in a Thai bank account for visa applications?

Why put the money in a Thai bank, when it can be in a wellknown bank in you homecountry.

How long does Bangkok require to have the $ in the bank account before applying for DTV? Sound like it has different requirement for different areas.

You should try a different consulate. In 4 months from now, most, if not all consulates will be on the e-visa system, most likely Laos as well (though so far, they haven't mentioned when they'll be moving to it).

What I'd be doing if I were you is waiting maybe a month or two and applying again in Yangon or somewhere other than Laos that is still accepting in person applications or relatively fast processed e-visas but where lengthy statements aren't required.

Ho Chi Minh requires 6 month statements BUT the funds can be recently transferred. Thus you would have been approved on the basis of the funds being in your account, however, since your bank account is still very new, that could be a problem there.

Anyway, wait until maybe mid to late October then see if an application in Yangon works for you.

I actually agree with this, I think Thailand is very smart, they don’t want people with very little finances coming into the country, they become a burden in one way or another, and they certainly don’t contribute to the economy of the country

Why will they care about an apartment in Thailand which has zero liquidity? A house in the USA is almost like a liquid asset, but they still don't accept it.

Did you fail after waiting for 2 working days or did they reject your application outright?

Out of curiosity, could it be a combination of 2 bank accounts ?

In an ideal world there would be one set of requirements about seeding the 500k that apply across the board. However, this is Thailand and even different Immigration Offices in country interpret the same requirements differently. Exam0les are Residence certificates? Extensions and TM30 requirements

It doesn't need to be a Thai bank account. It can be any bank account in your name. Is it an option for you to show the account where the money was prior to the transfer?
