Do I need separate bank accounts for my Thai visa deposit and daily transactions?

@Nongnuch *******

CM immigration require a 12 month printed statement from the bank.

I used the 800k deposit method for my 0A visa extensions for four years at the Bangkok immigration office. They want the bank letter and a one year bank statement. I use the same account for my 800k deposit and money I used for every day expenses. There is a column with the account balance and it is not difficult for them to just scan the balances. I also kept an additional 400k in the account as buffer to variations in monthly expenditures

when using the deposit method with 800,000.- THB in your account, Immigration only asks for a two month statement on the "rab roong thanakan" (bank letter of guarantee) and NOT for 12 months! You are confusing it with the 12 month bank proof of incoming 65.000.-THB for 12 consecutive months, month for month, for U.S. and U.K. citizens. When you hold a minimum of 800.000.- THB, you can use this account for your daily expenses as well, as long it does not fall below 800.000.- THB during the 3 months after having received the "extension of stay" ( NOT the "visa" . .the extension is NOT a visa!) and 2 months before applying for the new 1-year extension. Best is NEVER let it fall below. I use my "deposit method" account all year round, usually keeping 1.5 million THB on it. Immigration only ask for the two-month statement, I always ask the bank to give me a three-month statement. And that's what's to it
