Adoption is a legal process in which an adult person assumes responsibility for the care and support of another person (usually a child) who is not the adoptive parent's biological child. Intercountry adoption is the process by which you adopt a child from a country other than your own through permanent legal means and then bring that child to your country of residence to live with you permanently.

In Oklahoma, adoption is governed by state statutes that outline the legal process for an adult to assume parental responsibility for a child who is not their biological offspring. This process requires the termination of the biological parents' legal rights, followed by the establishment of the adoptive parents' rights. The Oklahoma Adoption Code (Title 10, Oklahoma Statutes, Sections 7501-1.1 through 7505-6.6) provides the framework for domestic adoptions, including the requirements for consent, home studies, and post-placement assessments. Intercountry adoption, on the other hand, involves additional layers of regulation, including compliance with the federal Intercountry Adoption Act, adherence to the Hague Adoption Convention (if applicable), and coordination with U.S. Citizenship and Immigration Services (USCIS) to secure the necessary visas and immigration paperwork for the adopted child. Prospective adoptive parents in Oklahoma must navigate both state and federal laws to complete an intercountry adoption, ensuring that all international legal criteria are met for the adoption to be recognized in the United States.
