Except as otherwise provided in AS 25.30.330, a court of this state may not modify a child custody determination made by a court of another state unless a court of this state has jurisdiction to make an initial determination under AS 25.30.300(a)(1), (2), or (3) and
(1) the court of the other state determines it no longer has exclusive, continuing jurisdiction under provisions substantially similar to AS 25.30.310 or that a court of this state would be a more convenient forum under provisions substantially similar to AS 25.30.360; or
(2) a court of this state or a court of the other state determines that neither the child, nor a parent, nor a person acting as a parent presently resides in the other state.
