Currently in USA and this is what I told to my brother who asked me same question? Bro Bachelors is all about studying and if you come to US without scholarship, its not gonna be about study anymore. It's gonna be more about work, money, party, etc....and at the end about study. So don't get too much attracted by American lifestyle or pictures of students in America, partying and stuff. But at least complete Bachelors in Nepal, so you can pay full attention studying. Then for Masters you can come to USA. Your life will be lot less distracted.
