   It shall be lawful for any person or persons to whom letters
   testamentary or of administration have been granted, by the proper
   authority in any of the United States or the territories thereof, to
   maintain or defend any suit or action, and to prosecute and recover
   any claim in the courts of the State of Oklahoma, in the same manner
   as if the letters testamentary or of administration had been granted
   to such person by the proper authority in this state, and the letters
   testamentary or of administration, or a copy thereof, certified under
   the seal of the authority granting the same, shall be sufficient
   evidence to prove the granting thereof, and that the person therein
   named has administration; Provided, that the courts in which any
   action may be brought by any nonresident executor or administrator
   shall have power, and such power is hereby given to the said court,
   upon motion, to require from such person the security required by law
   in a like case from a resident administrator or executor; Provided,
   further, that such executor or administrator shall have the authority
   to release mortgages in this state upon filing with the county clerk
   of the county in which such mortgage is recorded a showing properly
   certified to that such executor or administrator is the duly qualified
   and acting executor or administrator of such estate.
