Wow. I wasn't expecting so many replies so fast.
Schattenjedi, you made an good point. Personally, I am of Polish descent, born in Germany, and relocated to the US when I was about 5. I don't feel that living here has deprived me of my culture (not that it's my favorite country either). I simply find it interesting to study the Polish or German cultures and languages from time to time. As far as another person though, I never really considered whether or not such a culture-shift would affect their emotions or not. It is an interesting thing to consider, no matter where one adopts from.
As far as adopting from China goes, I am too young yet, as you have to be at least 30 years old to apply. Also, I find Japanese culture far more interesting, and would love to have the opportunity to teach a child that they come from something so great. The reason I would rather not consider adopting from here in the states is that there is a little known loophole in the adoption laws stating that if the birthparents ever decide they want their child back, they have before the child turns 18 to reclaim them if the courts find them fit. India, another place I considered, apparently goes by the laws of the adoptive parents' country, meaning US laws would still apply, placing the child in the same unsure position. I am still open to Korea or Vietnam, or anyplace that would both help the adopted child and allow our family to be legally secure. I was just interested to find some information on Japanese adoption, as there was so little available to find.
You are all absolutely right in that my biggest interest should be in adopting a child in need. After all, I am not adopting because of any fertility problems, I simply feel that it would be selfish to insist on a child of my own blood when so many others need loving homes. I didn't know what the conditions were like for the children there in Japanese orphanages, whether they were good or bad, or if there was a great need for homes.
Thank you all for your input!
