If you're from a wealthy family, then go ahead, enjoy your life. If not, think at least 10 times. Struggle here. Work hard here. The rewards are beyond imaginable. I can't say the same about Nepal. If you fail, your relatives, friends, family will be mocking you. No such case over here in the States. 

You gotta look at the bigger picture. Friends, family, food, you can have them aplenty over here too. 

I do also have friends working as Managers (MTs) in Banks. They make a decent living but they work like dogs and are severely underpaid. 30-45k when you're not considering the price of building a new house is great but what will you do in case of an emergency? Again, if you come from a family that's financially well-off, definitely go, else stay man.
