Ivy Universities appreciate international students a lot, because they usually perform very well. But their numbers are increasing exponentially, so they can't pick everyone
If you're a top notch student whith excellent grade in your international Baccalaureate or French baccalaureate. along with excellent grades in high school years. well, don't hesitate, go ahead and apply, its worth the chance
statistically speaking, a lot of Internationals go to CC first, perform extremely well, and then go to GREAT schools some of which go to IVYs (btw IVYs do not accept that many tranfers) .
