Are you a "qualified" teacher? If you are, you're not doing yourself any favors by working abroad. If you're not, it's the teapot calling the kettle at best for you.

Foreign teachers, whether they are qualified by western standards or whether they are not qualified by western standards are not always the best people to meet. Skeletons can be in anybody's closet including the ones with the proper qualifications. If you have been working abroad for a very long time, it would stand that things back home aren't exactly peachy. As it is, the fact that you would come on here and try to act like you know better suggests you've been doing this for quite some time now.
