I understand you don’t need a green card to study here. BUT your chances for acceptance as an international student are roughly half the %age of accepted domestic US students. And you won’t qualify for the same need based aid at many places. Other posters can verify. @MYOS1634 @DadTwoGirls
Maybe @Catcherinthetoast can comment about international folks and their job prospects here in the U.S. in the field of finance.
But to your subject question. Do what you love and love what you do. Don’t do things just because you think they will impress the adcoms at top 30 US colleges.
