(a) A court of the District which does not have jurisdiction to modify a child-custody determination may issue a temporary order enforcing:
(1) A visitation schedule made by a court of another state; or
(2) The visitation provisions of a child-custody determination of another state that does not provide for a specific visitation schedule.
(b) If a court of the District makes an order under subsection (a)(2) of this section, it shall specify in the order a period that it considers adequate to allow the petitioner to obtain an order from a court having jurisdiction under the criteria specified in subchapter II of this chapter. The order remains in effect until an order is obtained from the other court or the period expires.
