W. Va. Code § 15A-4-18
If a treaty in effect between the United States and a foreign country provides for the transfer or exchange of convicted offenders to the country of which they are citizens or nationals, the Governor may, on behalf of the state and subject to the terms of the treaty and with the consent of the offender, authorize the commissioner to consent to the transfer or exchange of inmates in his or her custody and take any other action necessary to initiate the participation of this state in the treaty. No transfer may occur pursuant to the provisions of this section until the inmate is informed of his or her rights and the procedures involved in his or her native language unless it is determined that the inmate's knowledge of English is sufficient.
