I've been thinking about teaching English abroad.

So, ya i'm wondering if anybody else has had this experience? What qualifications will i need? I keep hearing conflicting answers from different sources, a high school counselor once mentioned to me in passing that it takes a 6 week course at a community college and others tell me that you need a Bachelors in English to do so.

I'm thinking of teaching in Dubai right now.

So ya, just tell me anything i might need to know on the subject since i don't really know anybody who has done it, or anything about it.
