this document is just a translation of your original driver licence. It's a form stated by Geneva convention for e.g. to help countries recognise the driver/rider's capabilities/licence. There's absolutely no diference between the forms, only the paper which is slightly different fron country to country. I've seen a few ;) . Literally, nobody can tell who issued the form.
Normally you should get it in your home country as people say around here. But they all look the same as they are issued according to international conventions and basically it's a little note carnet with same papers in different languages. I also got a card that I wouldn't have gotten in my home country. I really wonder how anybody would make a difference of the issuer when you'd have to show it around 😃
I entered Thailand 2 weeks ago with VOA of 30 days stamped in the airport. Went to the immigration last week and they told me here they can only extend it for 7 days. Maybe depends also on your passport. My advice would be to read the official Thai page in your country as there are the newest and official info they will apply here.
