I agree with you som. I want to go back to Nepal after 10 year of stay here.
My plan is here, maybe you might have similar plan.
I am still a student.
I will graduate in 2 years.
Find a job. Probably buy house (this is for my investment). I might drop this idea of investing money to buy a house. I want to multiply my saving whatever I can save.
Work for 7-8 years here.
Sell the house if any and bring all the saving back home and start the life there.

For sustainable and improved life Nepal, we have to have some reliable source of income. I am thinking about some kind of business investment here so that the dollars will be deposited in the bank and we spend in rupees in Nepal.
