I have not adopted internationally; however we considered it seriously at one time. We ended up choosing to adopt from foster care, which is also an option to help children who are in bad situations.
Any adoption decision requires a lot of research - both about the things you will need to do/requirements of different adoption programs, and about the issues that an adopted child may have because of the things they've experienced in their lives. There are a number of books and websites out there.
If you have any questions, PM me and we can talk more.
