Get off your high horse, man!!!
As a Visa student, you don't teach classes; you participate in them. You're looking for a suitable option for a 6-8 month stay, and learning Thai cooking would certainly be a good option. Any chef can do this, a Cordon blue Chef or even a Michelin-starred chef.
Or are you that kind of chef who already knows everything and can't learn anything new?
