Oh I think that with a barack obama award + 710 + management experience at a wall street firm (plus international experience) should all come together to set you up not only as a STRONG candidate but also as a UNIQUE one. Having managers at both Columbia and NYU can be helpful and make sure you use that to the max. And I would prioritize those schools.
Otherwise, what are you waiting for???
Get started on those applications!!! you wanna get in as many as you can.
