Hello and welcome to JustAnswer. Please note: This is general information for educational purposes only and is not legal advice. No specific course of action is proposed herein, and no attorney-client relationship or privilege is formed by speaking to an expert on this site. By continuing, you confirm that you understand and agree to these terms. Under the Child Citizenship
Act, children adopted abroad automatically acquire U.S. citizenship if at least one of the child's parents is a U.S. citizen, the child was under 18, and the child lives in the legal and physical custody of the American citizen parent, the child is admitted into the United States as an immigrant for lawful permanent residence, and the adoption is final. So it sounds like she would be a US Citizen. If so, all you have to do is to get a US Certificate of Citizenship
for her to confirm this. See HERE. She can then get a US Passport. IF FOR SOME REASON SHE IS NOT A US CITIZEN BUT A PERMANENT GREENCARD HOLDER, then if she had a greencard (lawful permanent residence) and the document has expired, you can simply file to get a NEW one for her. The document expires; the status of permanent residence does not. Find the form HERE. AGAIN HOWEVER, if she is a US Citizen, then she does not need a greencard because permanent residence/greencard is a step below citizenship. So either she is a permanent resident, or she is a citizen - not both. I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished.
