If youve good savings, and good deal of property in nepal .i.e your family is rich, and your'e not doing much in the US, then you might be better off returning to Nepal.

if you've thought through many reasons why most Nepalese want' to go out, then you may go back.
few reaasons are
- high inflation but not much raise in income.
- no real honor of rule of law, or justice. 
- electritiy out most of the day or night every week.
- bad smell when you pass through any bridge.
- dust everywhere
- broken roads, 
- garbage is seen everywhere.
the list goes on and on.

so if you think you can deal with it, then go ahead.
