So I am an Indian citizen who spent 2-3 years of high school in another country and then went to the US for college to a top public (Berkeley/Michigan etc.) and majored in CSEE (Computer Science and Electrical Engineering) and Business - graduated with a 3.5-3.6 GPA on a 4.0 scale.
I spent the last three years working in management consulting (BCG/Bain/McKinsey) and interned at 3 F500s and another top consulting firm during my college career.
So am I still considered to be from the Indian pool, given I've been out of the country for over nearly 10 years now. How can I mention the other country (without talking about high school stuff)?
Second, am I still considered to be from the IT pool? One of my majors was CSEE, but I also majored in Business and have been working in consulting for 3 years now.
So am I an I/I/M?

If it matters, my top choices are Harvard, Wharton, Chicago, Columbia - and will probably do second round apps for Stanford, Kellogg and Sloan.
