Jim read the China article in the ESL resources/links section. Many deceptions. Salary offers are so low in China and foreigners still get charged more/conned for a lot of things. I was in Beijing last year and even the tour guide was stealing from us. There are also many health issues to consider.
The ESL industry in many countries is not about educating children but about opening a school and making quick money. Many directors in Korean/Japan/China cannot even speak to you in English and they have no teaching degrees, sometimes no degree at all. You will have a better working experience overseas if you look before you leap and examine the pig in the poke.
I am being honest (from experience) and direct so I will not say "Sorry" for telling people these things.
