IR-3/IH-3 Visas (approved Form I-600 or Form I-800)
The U.S. Embassy or consulate will issue an IR-3/IH-3 visa to your child if he or she is an orphan adopted abroad and the adoption does not need to be finalized in the United States. With non-Hague adoptions (IR-3) you (if you are unmarried) or both you and your spouse (if you are married) must have seen the child, before or during the adoption proceeding.
A child who has an IR-3/IH-3 visa may be mailed a Certificate of Citizenship after admission into the United States.
However, if the child lives overseas rather than in the United States—such as with parents posted overseas with a religious mission—then your child will be mailed a permanent resident card known as a green card.
A decision is made based on the facts of a case whether the adopted child is eligible for Certificate of Citizenship issuance.
