Iowa Code § 633.500

Notwithstanding any other provision of this probate code, if administration of the estate of a deceased intestate nonresident has been granted in accordance with the law of the state where the nonresident resided, the duly qualified administrator of the estate of the nonresident may upon application be appointed administrator in this state, unless another has already been appointed and provided that a resident administrator be appointed to serve with the nonresident administrator; provided further, however, that for good cause shown, the court may appoint the nonresident administrator to act alone without the appointment of a resident administrator.
