*** you got a monthly income/pension of 790,400.- THB which equals 26,201 U.S. Dollar ??
WOW!
Well that’s more than enuff to do the financial proof by the income method.
However it depends if the embassy of your passport country will issue an “affidavit of income” for the Thai Immigration. Some embassies have discontinued issuing such.
Which would leave you to no other alternative than having to prove a deposit of a minimum of 800,000.- THB in a Thai bank account in your sole name, for the first year of a “1-year Extension of Stay Permit based on Retirement”
