You shouldn't have a problem with immigration-- basically you need to get a job offer first with one of the two companies in Belize. The conversion is based on writing the exams bases on the British Overseas Air Law exams, and the companies take care of all the rest. Pay? I heard it isn't great but that is just a rumour. Practically everything seems to be single engine now-- I hear Tropic Air got rid of their Twin Otters favoring the Caravan-- Maya Island Airways may still have Islanders. Belize is a little expensive considering it is a 3rd world, Latin American country.
