Tommy, in an ideal world, qualifications such as teaching experience/academic studies etc. would be more relevant. As it is, yes, non-Native speakers with any of the Big Six passports ARE already currently teaching, in spite of not having relevant studies/previous experience, since these details may not be the crucial element that determines their being hired or not. As previously said, being a white face vs. ABC or other variations thereof opens the door. Passport gets you the work permit.
I personally would point out to the OP that there are other options besides teaching English. It may have been good money before, but nowadays…, and if he insists on going to the wild side, especially by walking in that crocodile’s mouth as an agent’s lair, the loses may surpass the earnings.
