I live just outside New York City, USA. I have been an elementary school teacher for 13 years. I recently have just got my principal’s license here in the states and am qualified to be a school principal here.

Could I get a good job ???

Given the current economic state and government cut backs, including the education system, and huge amount of unemployment I would say your chances are slim but research the net and send your CV to any possible establishments that are hiring.

Spid… even though you have great credentials, it is very likely you would have to matriculate to local ones…
This seems to be the norm.
as for what jobs would be available…
Very tough times here.
But that is not to say if you worked hard at selling yourself, that the right opportunity would come along.

Guessing you are a ‘casi perfecto’ Spanish speaker?
