With VOA you would most likely get 30 days extension from a day when you go there.

So, if you want as many days as possible - go there the day before your date on the stamp or at the last day as your stamp is showing.

I prefer going one day before the date on the stamp, because anything may happen last day (unexpected situation which wouldn't allow you to be there on time, unexpected to you out of office day or so...).

Are you sure that you need one?

@Wiz ******

thank you

@Erik ******

thanks for clarification. How does it work with that 1 week Thai cooking class? I have income from an online business registered in a Western country, but I see some hurdles with providing all necessary documentation to prove this. Idea about 1 week Thai cooking class seems much easier. How would I proceed with this? Do you have experience with successful application for DTV this way?

@Erik ******

isn't for a DTV visa 500k THB requirement?

when you merge all documents into one PDF file and it's still too big, Google "PDF compressing online" to make the file smaller with a free online tool.
