nope, the official announcement mentioned nothing about the cost or requirements for an in country extension. The official announcement came from the MFA who is responsible for the Embassies that issue the visa. There has been no official announcement from the Immigration Department that are responsible for in country extensions. It’s very simple - nobody knows the cost. Anyone who tells you different including the quoted websites are misleading you.
that is a business website that is guessing what the extension will cost. Nobody knows what the requirements will be for an in country extension nor the cost as the Immigration Department has yet to officially publish the requirements.
can you give a source of information that Thai Embassies accept Wise statements to satisfy the financial requirements for the issuance of visas? It’s easy to say but can you back it up with facts?
Bangkok Bank Jomtien requirements: Long term visa, passport, 2nd government issued photo ID, residency certificate, 1 year lease agreement or blue book. Every bank and every branch will have a list of their own. Just give you an idea.
I have read instances of people getting the medical DTV with just a single hospital or dental appointment. It really all depends on which embassy you are applying to.
