“Every person who is domiciled in this state may hold property
exempt from execution, garnishment, attachment, or sale to
satisfy a judgment or order, as follows: . . ..” Ohio Rev. Code §
2329.66(A).

This state permits only its domiciliaries to use its exemptions.  
Therefore, if it is the applicable state (as determined by the
method stated on the home page of this site), its exemptions
may be used only if the debtor is a domiciliary of this state on
the date of filing bankruptcy.
