What are the requirements for the combination method of qualifying funds for a Thai visa renewal?

Ok, so just did my 90 day report in Koh Samui, So thought I'd include this for information.

No mention of the TM30.

While there I also enquired about using the combination method for the qualifying funds.

I do not want to bring money over while the rate is so low, so wanted to do it this way. The very helpful lady said that I have to show two documents from the bank. 1. As per normal, letter stating my current balance. 2. Letter showing international deposits on a monthly basis for the last 14 months.

She said it would be better to include the two month qualifying period as well.

Seems straightforward, but I renew in August, so let's see.

Hope it's helpful.
