Yeah, I'm not a teacher. Though I do hold a legitimate TESOL accreditation. I know a lot of teachers here and none of them make my wage. I would not enjoy working in an "international school".
It's easy to fuck around with fake documents, but I've seen people lose their reputations over silly shit like that. The tickets and accreditations related to my trade will be used for visa applications as well as jobs. I'll just do it properly. It's easy stuff and there's no huge panic on.
K, - it's a nice part of the world. But I wouldn't know where i'd settle again right now if I were doing it again. The region has been undergoing rapid change. Worth touring some!
