I agree with etopf. I might also add that with Ethiopia things are moving pretty fast. Also the babies are coming home under 3 months. From what I have heard (have a friend thinking of adopting a girl from Ethiopia and she has done a ton of research) the program has really ironed out its problems and I don't think it will close down if things keep moving in the direction it is going. Here is how would decided.
Want an infant girl with about an 8 month wait = Ethiopia. Want a girl age 12+ months with a wait of 24 = Korea.
From what I understand with all agencies the youngest child in the home must be age 1 before an adoption can take place (not before you start the paper work).
Good luck and keep us posted : )
