International child custody case - plz answer

in this case if chid USA cityzen than indian court rules not apply on this child so mother did not file case agianst case custody but first you talk with local lawyer also 

Jurisdiction over custodial rights of a minor U.S. citizen will remain with U.S. Courts but depending on other circumstances, such as citizenship of the parents, the Indian Courts may have concurrent (also have) jurisdiction if the child lands in India and is in India at the time of the custodial dispute.
