Have a pulse. Congratulations, you're now a Saba student.
I'm being reasonably sincere- interviews as of late at most of the Carib schools are more a formality and a brief check to make sure you're not out of your mind than they are actually a part of the selection process. You'll get in, just be yourself.
Then I'm sure you've done the research on the dangers of the Caribbean for med school. It's always good to try to do whatever you can to improve yourself and your application for US based schools as a first line option. But, its your life and your decisions, so take it for what its worth.
