You can e-mail me with questions. I am brazilian and my husband is American. It is very difficult and almost impossible to adopt an infant from Brazil, even if one of you have brazilian citizenship. The adoption process is complicated and I do not recommend you doing it independently.
We were not able to adopt an infant in Brazil, we adopted our children from Colombia and Guatemala.
I will be glad to answer any specific questions, as I have done a lot of research on adopting from Brazil and ended up not being able to do so.
