There is a couple who wanted to adopt their foster child. Certain folks in the foster system wanted to send the child back to the natural mother, who is apparently "getting her life together". The case dragged on for years but the judge ruled in the foster parent's favor.
Whenever people say "I don't know why So-in-So did a foreign adoption. There are plenty of kids available in foster care," I just sigh. Just because a child is in foster care doesn't mean they are free for adoption. There is a parent or a relative out there who for whatever reason won't let go and the kid can languish from foster home to foster home to group home until they turn 18. And then there's the other thing. Not all foster parents are nice people. Some treat the kids like crap. Adopting an older child from foster care means that you run the risk of unknowingly taking on a child who is severely damgaged. Not everyone has the strength or financial resources to handle that.
When the guy in accounting or the woman from your church choir does a foreign infant adoption give them a break before trotting out the old,"plenty of kids right here," line.
