Bula from Fiji
Hoping that you'll gain help and useful information from the forum.
I'm not sure in what you plan to teach, but whatever it is, if hoping to gain an income
you'll face the problem of work
restrictions in almost the entire Caribbean, (which of course is made up by some 26 different countries). As a generality it is very difficult to get a work permit
anywhere unless you're a citizen or at least gain permanent residence status. Good perhaps I am reading your post incorrectly.
Anyways do feel free to post your own thoughts, questions and ideas here on CF. The forum only works when people post, and 95% of members here seem reluctant. Don't be a lurker. Also please fill in your profile so we all know something about you (I've no idea where NC is or even to which NC you refer).
