Oklahoma has opted out of the federal exemptions for  
residents. “No natural person residing in this state may exempt
from the property of the estate in any bankruptcy proceeding
the property specified in subsection (d) of Section 522 of the
Bankruptcy Reform Act of 1978, Public Law 95-598, 11 U.S.C.
A. 101 et seq., except as may otherwise be expressly permitted
under this title or other statutes of this state.” Okla. Stat. Ann.
Tit. 31, § 1(B). Therefore, debtors who are not residents of
Oklahoma are eligible for the federal exemptions.
