What level do you have to be to teach it in a foreign country?
None. I nearly taught english in China. But I had more pressing commitments at the time to take care of. I have no teaching experience. Just a gift to talk and several phone interviews with chinese employers. If you have the right attitude, can communicate and most of all explain yourself. Then you can do pretty much anything. Since you are on this website. A student who is being educated has gone thru the stages of academic rules and bureaucracy. Treat it like a interview at a universty and wow them.
