Kan. Stat. § 73-515b
The order for care or treatment of a person determined to be a mentally ill person entered by a court of competent jurisdiction of another state or of the District of Columbia, which orders a person to the veterans' administration, or other agency of the United States government for care or treatment shall have the same force and effect as to the involuntary patient while in this state as in the jurisdiction in which is situated the court entering the judgment or making the order; and the courts of the state ordering such care or treatment, or of the District of Columbia, shall be deemed to have retained jurisdiction of the person so ordered for care or treatment for the purpose of inquiring into the mental condition of such person, and of determining the necessity for continuance of his care or treatment; as is provided in K.S.A. 73-515a with respect to persons ordered for care or treatment by the courts of this state. Consent is hereby given to the application of the law of the state ordering such care or treatment or district in respect to the authority of the chief officer of any facility of the veterans' administration, or of any institution operated in this state by any other agency of the United States to retain custody, or transfer, or place on convalescent leave or discharge the involuntary patient.
