Yes dear, there are laws. This laws vary from one country to another. You should also note different adoption centers have their own laws too. There ae some that might allow her. While others may not. She should expect any kind of answer. It could be best if she did internet research. Or she goes to adoption agencies. In S.A they might be of help. That way she will learn more. She will also be educated on their rules. Like what laws govern their adoption facilities. Being there for 5 years might be long. But what most adoption centers will want to know more. What if she leaves the country and never returns back? What if she starts mistreating her bad while away? There will be a lot of questions that she will have to answer. Mind you the child has the citizenship of that country. If she returns with her back to America will she have dual citizenship? She should just be prepared to be interrogated.
