If the marriage took place without the approval and consent of the father of the girl, this marriage is void, You must repeat this marriage contract. But if the marriage was done correctly, You can keep a gathering to announce your nikah when you are back to your native country but without a repetition of the marriage contract.

Is it permissible for someone to do nikkah with the same person for a second time? For example if both were studying abroad and already conducted nikkah but then when they are returning back to their native country their families want them to re make the nikkah… is it permissible in islam?
