Upon the filing of the petition, the circuit court shall, upon being satisfied as to proper jurisdiction and venue, immediately enter an interlocutory order or an order referring the case to a child-placing agency to conduct an investigation and prepare a report pursuant to § 63.2-1208. Upon entry of the interlocutory order or the order of reference, the court shall forward a copy of the petition and all exhibits thereto to the Commissioner and to the agency that placed the child. In cases where the child was placed by an agency in another state, or by an agency, court, or other entity in another country, the petition and all exhibits shall be forwarded to the local director or licensed child-placing agency, whichever agency completed the home study or provided supervision. If no Virginia agency provided such services, or such agency is no longer licensed or has gone out of business, the petition and all exhibits shall be forwarded to the local director of the locality where the petitioners reside or resided at the time of filing the petition or had legal residence at the time of the filing of the petition.
