Hi asn88 and welcome to Admissions Boards!
Your chances of admission rely on more than just your GPA. You also have to take the MCAT and do well on it and you would also have to address any medical volunteer experience in you application as well. With only your GPA, I can honestly only speculate about your chances of admission. As far as schools in the Caribbean, I would say avoid them, it will make earning a job in the U.S. extremely difficult for you in the future.
Best of Luck!
