As of late, (Sep 2012) postings have been for ATR First Officers. As last couple posts suggests...there are alot of pilots waiting for interviews from that posting as well as the initial pool back in Jan/Feb 2012 who have not received a response.
Restrictions are always: "When recruiting, prefer to hire Trinidad and Jamaican Nationals" although, they do state that they may hire highly experienced foreign nationals on short term contracts. So it may not hurt to try.. but right now, your guess is as good as mine.
