I'm interested to see if an extension is possible with that course. I get the feeling that immigration won't give extensions on it with some Thai embassies rejecting it for DTV. I guess we will find out soon. If it works then it's a very cheap course for 5 years π
It actually looks like a scam course. It doesn't appear to be real. I think it was set up just to profit from the DTV. Sounds like some people got approved with it cause the embassy they applied at didn't look into it too much. But anyone with half a brain can tell just by looking through their website that it's not a real course
