Be careful with China. Many good jobs can be found in China, but I've read many a nightmare story about that place. Yes, the reason for those stories may be the fact that China is so big, but I'd keep investigating before deciding on China.

If you like teaching kids, you'll be better off going to South Korea. You'll get paid lots more and you'll probably get your air fare reimbursed. Many a teacher who's been there will say SK isn't that great, and he/she may be right. Just remember, though--apartment deposits in Seoul are at times over 5 THOUSAND dollars (or more) for a year rental. If SK, especially Seoul, DID suck so much, no one would be putting that kind of money down on deposits to do a teaching job for a couple of months. But lots of people do, which tells us what? They're confident the jobs will be worth it and will last at least that entire year.

If you decide to do SK, don't sign your John Hancock on any contracts simply based on someone else's descriptions--go there and check out candidate schools first. Accepting someone's glowing descriptions about a school, be that person a director or even a teacher, is a common way we TEFL grunts get burned.

P.S.--Most schools in China can't even legally hire you on anyway, and SK doesn't require a TESOL at most jobs.

Good luck.
