6 year foreign med school or go to college and do premed?

-btw I posted something similar to this in the MD + high school forum a few weeks back- just wanted some input from foreign grads now- I'm a 17 year old high school senior, and I have to apply to colleges soon. I'm interested in the health field, but I'm not 100% sure yet if I want to be either a doctor (Pediatrician) or a Physician Assistant (PA). I want to go to a U.S college and either complete pre-med or pre-pa, I might even do pre-health since I don't know which health field I want to... 6 year foreign med school or go to college and do premed?
