Money has to be in Thai bank. Or if you have cpf payout monthly which satisify their monthly requirement, can ask Sg embassy issue you a letter stating you receiving xxx sgd equal or more to 65k THB a mth.
Gd luck.
Taken from Siam Legal:
Must meet any of the financial requirements:
Security deposit of THB 800,000 in a Thai bank account for 2 months prior to the visa application
Monthly Income of 65,000 THB
Combination of security deposit and annual income with a total of 800,000 THB
Supporting documents are as follows:
In case of security deposit, you will provide an updated bank book or passbook together with a bank letter stating that the money had been deposited to the account from an overseas source for not less than 2 months.
In case of income, a letter from your embassy in Thailand verifying your monthly income; or should your embassy does not issue an income letter, you will provide a 12-month bank statement showing a regular deposit of 65,000 baht into a Thai bank account
About the 800000bht method to apply i have heard that it needs to be in thai bank account. If i am currently in sg and wants to apply from sg, can the money be in local bank? Will embassy accept? Also about the medical certificate does anyone knows of doctors who can certify? I brought the cert to my GP but he says he can't do it.
