Columbia, Brown, and Haas

I am a non-traditional transfer student and I recently got accepted to Columbia GS (Financial Economics), Brown(BEO), and UC Berkeley Haas School of Business (Undergraduate, not MBA)

I am quite different than the most who goes to these school, so here is little bit more about me.

I am 26 years old (as I mentioned before I am a non-traditional student with some life experiences including military duties in Afghanistan and etc), international student (meaning I have a student Visa to study in the U.S.), never graduated high school in my life, low income, and Asian male.

My primary concern is that I would be an extreme minority if I go to Columbia or Brown.

Let's face it, the real value of Ivy is the connection, but I don't know if I can reap the benefit given my background.

So what would be the best school for me if I want to stay in the U.S. and get a job in consulting or banking. (2nd tier firms are fine too)

I am shooting for consulting but I focus my study mostly on finance to open a door for banking as well.

Any advice for me regarding which school would be best for me?

P.S) I heard so many things about Columbia GS students are second citizen at the Columbia University. Is this true? If so, does it affect my recruiting chances and what not? Do companies care about CC or GS?
