If anyone interested what is the check list I got from CW as it may serve you as a general reference, but visit yourself to clear all details

Ok, got it, thanks. Still have more than 15 days on my stamp. Then will go to CW.

Yes, have in mind yearly extension. About letter seems like straightforward. What about bank book? Lets say I have opened bank account 2 months ago but haven't add funds anything close to requirement and only will do that close to the extension applying date. Will it raise some questions? Since they can see bank books history and it won't show that that amount has stayed there for 2 months. Thanks

Could you please elaborate more on “financial requirements of 400K baht banked in a thai bank account in your name only for 2 months”

How do I prove this statement? Do I provide some kind of financial certificate from my thai bank account or do they (authority) have access and can get information directly from bank? Or anything else?

For example, in my country, if you wish to apply for METV but your status are unemployed you do have to provide statement from the bank that you do have required amount of sum. In case you don’t have required amount of sum, you might ask for your friends, parents and etc. to lend you for the purpose of the financial statement and after that return them back their moneys. Will it would work here, in Thailand ?

As I am not willing to exchange Euro’s to baht just for this requirement. Thus, would want my Thai wife or friends lend me that amount.
