For opportunities outside of Belize please buy the latest edition of: TEACHING ENGLISH ABROAD by Susan Griffth.
You can also go to the best web site on the subject at:
http://www.daveseslcafe.com The hottest areas are Korea
and China.
In Europe they greatly respect the Cambridge TEFLA certificate
but in China and in Korea you can get by on a college degree only. Central and South America are low paying.
If you want to save some money in the bank from your teaching career so you are not just getting by then go to either Japan, Korea, or an Arab country in the Middle East which I would not recommend unless you like having someone put a black hood over your head and appear on TV with guys who are holding guns etc. ;- )
