I do think things are different now. I don't know that I'd recommend for anyone to go to med school (US or foreign) if he/she can only imaging being happy in 1 or 2 fields of medicine. This is because nobody (US or foreign grad) is guaranteed to get a spot in the fieldy of his or her choice.
Doing plastics is damn near impossible from the Caribbean. Even US students who go somewhere like Duke, Emory etc. and do well would be sweating bullets trying to get a plastics residency. It's a function of how few spots there are and how many people want in.
If your dad is a doctor, why don't you consider a US school? Why don't you think you can get a shot there? With a dad who is a doc, you should be hooked up for clinical work, shadowing, etc. Is the MCAT giving you big time problems?
