I want to become a fashion designer BUT..(advice needed!)?

I am 16 years old, and i'm very sure that i want to head into Fashion for a career. Problem is, on the island I live, there are no fashion institutes or any Magazine outlets [Vogue, Teen Vogue, Elle] that I could work for in the near future [as an intern, for example]. So since I am going to college and going to study art with other subjects as well, could anyone help me with what I can do after? Do I need to leave my country for sure to succeed in becoming what I want? The closest fashion school near my that I can think of is in Italy which is still a pretty far away place from where I live.
