Yatuti, It's a great thing to hear that you are heading back home with a strong belief that you would do something. I really respect your thoughts and what you are going to pursue.  Here is my piece of advice. Yesterday you were asking about the benefits of being a US citizen. Tell you what, apply for citizenship wait another 3-4 months by then you would get your US citizen. Go back to Nepal and do whatever you want to. Just in-case later if you feel that its worthless and you feel that you were just another fish in the sea you still wont have any trouble heading back to US.

Best of Luck,
