What might seem like a "good job or trade" today might not be in high demand 5 years from now. Besides that, if you take 5 years to re-train for a new trade where you have little or no experience you'll be looking at entry level positions when you are finally ready to reenter the work force. Those entry positions won't necessarily be high paying and who knows what the market will be another 5 to 10 years down the line when you have "real" marketable experience.
Unless there are quantum leaps in the healthcare procedures which drastically change how patients are treated radiology technicians and psychologists will be still be needed so why not do as speee1dy suggests and spend the next 5 years pursuing employment opportunities in the areas where you already have experience and training. Doing so successfully will make your skills more marketable and hopefully give you a leg up on your competition 5 years from now when you are ready to make the move.
Finding employment in the USVI's isn't all that much different then finding employment anywhere. You have to a skill that is needed at the time you are seeking employment and you have to demonstrate your skills, personality, work history and and ability are better than the other applicants. Ask yourself, if you were doing the hiring for an important "well paid" position - would you want someone fresh out of "trade school" with no experience or someone with a proven track record .
