There is no easy answer to this question. I have done an inter-family adoption and immigration from Brazil. it was a complicated case and involved many steps and a long time. You will need to hire an immigration attorney here in the U.S., find one with Hague Convention adoption experience. You will also likely need to hire an attorney in Brazil. We have an attorney with our firm who is licensed in New Jersey, practices immigration law, and speaks Portuguese. 203-373-9080.
