Adoption,
Unicorn is right. It is very difficult these days legally to adopt from Nepal, unless you smuggle them. Some sinful people ruined lot of children's future for Nepal. I would adopt from Nepal in a heart beat if things were faster and easier.
I think you still can, but it will take a long time. Many years ago when things were good in Nepal, few of my friends (white families) adopted from Nepal, 3 family adopted 5 kids. They told me it took them 5-7 years to complete everything. If I am not wrong, I remember them saying it cost them around 50K in those days.
But now with the stories of child selling, it will be even longer I assume.
Adoption is a very lengthy process. The easiest ones are from Africa. I know a family right now in line for 2 years to adopt a baby from Ethopia. They "might" get the baby girl this year, but again, things can go wrong anytime in Africa. They tried once from Congo but it fell through.

If you don't have that much time, I would recommend adopting right here in America, it will be lot faster. Don't be too picky on the race/gender of the child, then you have a high chances. It will still cost you form 15K-25K in total.
How do I know this? I tried once but had to cancel my plan for a while. I might start the process again soon. I will be adopting a child right here in the USA.
Keep us updated and Good Luck.
