Well dude going back to country is not a bad ideas and giving something for our country. Now a days there are lots of people who have done master and worked in banks, finicial instutation and colleges are ta growing like momo pasal. We can try in banks, NGO, INGO and college. You have very strong degree. If you get not happy with  nepal and what u do there then i suggest you to try Canada, England and Australia they have lots of benifits now days for international students  for PR and Work permits. THese nation are coming up with better economic without any mess like usa.so i adivise nepal give something to ur country  then think other nation.

All the best.
