My parents adopted my sister from Russia about 20 years ago. At the time, Russian law only allowed foreign adoptions if the child had a physical or mental disability. My sister had a crossed eye, that was sufficient to allow her out of the country. She is now 22 years old, going to college, and living a happy, healthy life. Some friends of my parents adopted two children from the same orphanage, a brother and sister. The brother had serious issues - trying to kill his parents and run away at 6 years old type thing. They eventually placed him in the home of parents with no other children who were looking for a child like that to care for, I lost track of the story after that. The sister is also leading a normal, ostensibly happy life, though.
