We are adopting from Ukraine :)
Im trying to learn as much Ukrainian as possible before we leave to get our kids.
Congrats :) How old are they? Do they speak Russian too?
It's so nice that you want to learn their language. They will appreciate it even though if you learn only basic phrases.
May I suggest doing reverse tree (English from Ukrainian)? It helped me a lot with my Ukrainian.
So the way it works in Ukraine is... You are given an appointment with the government and shown orphans that fit your criteria. Then you have 2 weeks to bond with the kids and they decide if they want to be adopted. It takes another month or so to get all the paperwork complete.
