At Kalasin it has to be at least ฿65k deposited every month, but it doesn't have to be all at once, for 12 months. They also wanted to see proof of where the income came from in your home country, tax receipts, a letter from your company pension and or government pension. Things like that.
For those that use a Letter of Income, I suggest you set up a bank account in Thailand and transfer ฿65,000 every month. For 16 years I used a letter of income from the Canadian Embassy in Bangkok. Then last April with about 1 month notice the Canadian Embassy stoped issuing the letter. Fortunately after the US, UK, and Australia stopped issuing them I opened an account in Thailand and made sure I deposited ฿65,000 every month, so when Canada stopped issuing the letter I was prepared.
I saw that, but when I'm passing through an airport I quite often pick up a bit of the local currency, usually more than I need, I just wanted to warn you in case you did the same.
I'm not sure but it looks like you may be Canadian. If so I heard that as of April 01 they were no longer issuing letters of income. Perhaps you got one before then.
