One of our main reasons for adopting from Russia was the speed in which the adoptions took place

.
We are very imatient, and were told that Russia is typically 6 - 9 months, start to finish. Well, we're glad we moved forward with Russia, but our process took closer to 17 months

.
Other than time, we too made a pro con list. During this process, we completely ruled out domestic due to open adoptions. We also ruled out Asia and S. America due to ethnic differences (if we were adopting an only child, it may not have mattered, but with a bio son already, we wanted them to be as similar as possible). This left Eastern Europe. We went with Russia because of our interest in traveling there, abundance of children, and another family member being born in Russia (adopted neice).
Good luck with your decision.
