Do NOT apply to Carribean schools. With changes in rules you will NOT get a residency and will not become a doctor. If you cannot get into even one DO school after two application cycles, you’ll have to switch career goals.
Really, you’d have MUCH higher odds of working in healthcare if you completed requirements for a nursing degree and pursued it to NP which would give you a lot of autonomy in patient care, or if you prefer the physician’s approach, the PA track who works as a general practitioner.
You’d essentially do the same job in less time, would make an excellent salary, and most importantly wouldn’t be going against odds that make it almost impossible for you.
