Fees will be anywhere from 7000-15000 for cheap universities for a semester. So 15000-30000 $ per year, provided you earn living cost working on side. If ur father can spend 20 lakh per yr, u can do it. Otherwise life will be 100 times harder than u imagined. 20 lakh ma ta u can easily get whole BE from nepal/india. In grad school u can get scholarship and TA/RA , so instead of having to pay a fee, u will get ~1500 per month. So u will be saving money. Ask not ur friends ( they mught be ashamed and tell u a lie) but people who have gone on grad school and done it.
