    Sec. 711. Modification of Convention child-support order.
    (a) A tribunal of this State may not modify a Convention child-support order if the obligee remains a resident of the foreign country where the support order was issued unless:
        (1) the obligee submits to the jurisdiction of a
tribunal of this State, either expressly or by defending on the merits of the case without objecting to the jurisdiction at the first available opportunity; or
        (2) the foreign tribunal lacks or refuses to exercise
jurisdiction to modify its support order or issue a new support order.
    (b) If a tribunal of this State does not modify a Convention child-support order because the order is not recognized in this State, Section 708(c) applies.
