New User instroduction and future Major conflict

hello,
first time writing on the forum. I guess I should introduce my background first. I was born in Seoul, South Korea and came to the states when I was 10. Did all the normal kid things and recently begin to realize I need to put my self together and do something productive. Did alot of thinking in Korean airforce, which i'm part of until this July. No, I'm not a US citizen(therefore, needs to get sponsored), which makes it shit hard difficult to get a job in the states especially with the degree which I'm getting towards.

the goal? I want to break through the barrier of I-Banking or consulting firms.
I do not go to a top targeting school, but I go to Emory Goizueta. That said, the major conflict rolls in. Goizueta is a two year program business school after studying at the Emory college. They offer five concentrations on the major and I always leaned towards the Finance since it seemed the most appropriate for I-banking and consulting firms. Recently did I learn that it was not enough just earning a Finance degree, but should major in Accounting to become basically qualified for IB. I have two years in school left but I dont have the academic time to finish two majors at once. Since IB is such a high risk, and failing to break the barrier of IB would result me probably going back home and finding a job there, I was looking towards an simply accounting degree and get a CPA, which will land me a some job in the states. Also, we have a major called ISOM, a combination of IS and OM which seems to interest me but may not be the most economic decision for all the tuition payed for the school. ISOM seemed to look good for consulting firms, but really I cant trust any of the statistics and my background may make me an exception.

Just want to hear others thoughts and info if you guys have some.
