Have pulse, white skin? Will travel.

That's all you need to teach ESL in China. If you want to go to Korea, you need a degree as well. China says you do, but lots of crap schools don't require one.

Truth is a degree is easy to come by here ;)

I'd suggest another line of work though, because pay and working conditions are not good, unless you teach in Europe, and even than you may get shafted.

My advice, stay home, find another career path.
