You’d need a school in NYC - research merit awards (conditions for full tuition scholarships or full rides) at FIT, Fordham Lincoln Center, Marist, Suny Oneonta-FIT, perhaps Baruch (?) and Pace (?).
I agre with katliamom, places with lots of fashion opportunities are also likely to be the most costly, so you may have to choose between your need to be in the US and your need to study in Fashion PR.
What other major could you consider?
Have you taken the SAT/ACT yet? Any score?
