Medical and Healthcare Jobs

Most of the in demand work abroad are medical and healthcare jobs. They need caregivers, nurses and even doctors to fill up their hospitals and home of the aged. And since I have a dream to migrate and work abroad, it made me think if I should go back to school and pursue a course in medical and healthcare. If I take nursing, it would take me another 5 years to achieve it including review and passing the board. But if I study as a caregiver, it would only take me 6 months.

Anyway, I know there are still a lot of options but most of my friends say being in the medical and healthcare field is the easiest way out to work abroad. Now, what shall I do?
