My Sister and BIL are in the process of adopting. It is a long and very difficult path to adopt (especially for an infant), but it does provide a good home ("verified" by several different people) to a child who would otherwise grow up in a foster/orphanage.
I was actually thinking about a foreign adoption. I've read where up children in former Soviet bloc countries (The Ukraine in particular) are booted from the orphanage at age 15 and the majority of the boys end up in organized crime and the majority of the girls end up in prostitution. It's absolutely heartbreaking.
Some friends of my parents did that. For whatever reason they were unable to biologically have a kid, and they adopted one from Russia. I've never met the kid, but it sounds like they are doing ok. They went there to pick the kid up, and the thing that struck them was the rampant alcoholism. Their host family opened a bottle of vodka with every meal. You didn't leave the table until the bottle was kicked.
