how do i get jobs teaching English overseas?

I am really interested in going to other countries especially Asia, Eastern Europe, Middle east and North Africa. I hear about teaching English and would be thrilled to do that. I am currently a political science major. I am currently trying to learn to speak Arabic, Farsi, Urdu, Hindi, Turkish, Vietnamese, Russian, Mandarin, Japanese, Tagalog, Italian,and Spanish by cd. I feel i could be fluent in another language in 6 months if i have the ability to practice it more. I would also like to finish college in a foreign college.

my gf use to tell me she doesnt speak her native philipino langauge, but the other day i heard her speaking it with her mom. same with some friends at work, they say dont speak vietnamese/urdu, but i catch them speaking it. why?
