<p>For NYC opps, you want to attend Wharton or another top American school. Likewise, for London opps, you want to attend European schools. If you are striving for the top investment banks in NYC, going to school at Oxford or LSE would place you at a disadvantage simply the American firms strongly prefer well-rounded people who can excel in any discipline. Students who concentrate on a major or two for three years at Oxford, LSE, etc. simply aren’t as desirable in eyes of top banks in NYC. On the other hand, opps in London prefer applicants to know their econ, thereby preferring applicants from British schools.</p>
