There are a few possible fields
PA/NP/other midlevel- less school than an MD. Good prospects for the future, not a lot of debt. That said you wont be the leader, so if that is impt for you, well cross if off.
MD- most expensive, most time consuming, most well respected, best paid. Huge pros and cons.
Carrib MD- larger hurdles to get into the US, no gaurantee you will graduate, pass the USMLE or match. Large financial risk. If you end up matching in to what you want, all those issues disappear.
US DO- simialr to carrib MD but fewer "what ifs". Have possibility to match into DO residencies in addition to US ACGME programs (MD residencies). Still regarded less than US MD
Pharm- less debt than med school, fewer years of school, no residency. Personally I think this is a crappy alternative. Most end up counting pills in a walgreens. No real autonomy, no real pt contact. Good hour flexibility. Take it for what you will.
Dentistry- 4 yrs school so similar debt load to med school but you come out practicing. Less hastles with insurance and malpractice. The downside is you will be dealing with cavities, cleanings and crowns for the rest of your life.
Other options include OT/PT (physical therapy), nursing or low level providers.
