S.C. Code Ann. § 20-7-1670
(A) Any South Carolina resident may petition the court to adopt a child. Placement of children for adoption pursuant to Subarticle 7, Article 11, Chapter 7 of Title 20 is limited to South Carolina residents with exceptions being made in the following circumstances only:
(f) the child has been in foster care for at least six months after having been legally freed for adoption and no South Carolina resident has been identified as a prospective adoptive home.
Before a child is placed within or outside the boundaries of this State for adoption with nonresidents of this State, compliance with Subarticle 11, Article 11, Chapter 7 of Title 20 (Interstate Compact on the Placement of Children) is required, and a judicial determination must be made in this State that one of the circumstances in items (a) through (f) of this section applies, whether or not the adoption proceedings are instituted in South Carolina. Additionally, in order to determine if any of the circumstances in items (a) through (f) of this section apply so as to permit placement with a nonresident for the purpose of adoption or adoption by a nonresident, a petition may be brought for the determination before the birth of the child or before placement of the child with the prospective adoptive parents. In ruling on this question the court must include in its order specific findings of fact as to the circumstances allowing the placement of a child with a nonresident or the adoption of a child by a nonresident. The court also must analyze the facts against the objective criteria established in Sections 16-3-1060 and 20-7-1690(F) and make specific findings in accordance with the pertinent law and evidence presented. The order resulting from this action does not prohibit or waive the right to refuse to consent to a release of rights or relinquish rights at later time nor to withdraw a consent or relinquish at a later time as provided in this chapter. The order must be merged with and made a part of any subsequent adoption proceeding initiated in South Carolina.
