I agree with bairaghi bro. Life in the US is not like what people might show off on social sites. Especially if you come here for undergrad, chances are most likely you will get screwed. Unless you are a very talented student with a 100% scholarship and doesn't need to work off campus to support yourself, you're most welcome. But, with a 50% or so scholarship, please save yourself and invest the money back home, graduate, take the GRE and then apply for masters. But then again, what's left there in Nepal these days? :( I can understand the frustration of our youths of the nation.

Explore the options. After all, you are the one to make your decision. I hope you make the best one.

Good luck!!
