hi folks

i have a question about 400000bahts in bank account, can the officials ask about the origin of this money.

or in other case 800000bahts for retirement visa in bank account, can the officials ask about the origin of this money?

thanx

Banks and other financial institutions do monitor/identify the transfer of illegal funds within and outside Thailand.

I applying for a "conversion" to non imm "O" visa within Thailand the origin of funds may be questioned.

There is no requirement to prove where the funds came from if applying for an extension of stay

If applying for a non immigrant visa at immigration they require proof the funds came from abroad. They ask for that since there is no requirement to have the money in the bank any longer than the date your apply for the visa.
