Okla. Stat. tit. 21, § 21-65: Civil rights suspended

A sentence of imprisonment under the Department of Corrections

suspends all the civil rights of the person so sentenced, except the

right to make employment contracts, during confinement under said

sentence, subject to the approval of the Director of the Department

of Corrections, when this benefits the vocational training or

release preparation of the prisoner, and forfeits all public

offices, and all private trusts, authority or power, during the term

of such imprisonment. Provided however, such persons during

confinement shall not be eligible to receive benefits under the

unemployment compensation law.
