Since the British Embassy ceased issuing confirmation of income letters in 2018, I been using the 65k a month method to obtain my retirement extension. I’m now seriously thinking of changing to the 800.000 Baht deposited method. I’m aware of the need for this to be deposited 3 months prior to applying. Is there anything I need to do to change methods, or do I just go along with confirmation of my 800,000 Baht deposit from my bank.
