You can register your marriage with the authorities in Pakistan if you have a permanent residence address in the country, but the authorities are not fussy about checking if the address is really permanent.

Pakistan is an outstanding place to begin your life together. You can swim or snorkel or lay a blanket on a deserted beach and just relax. If you want wild and crazy nightlife entertainment, its easy to find. The historical sites, natural attractions, shopping and recreation are hard to beat. And the wonderful, delicious Pakistani food has no equal.
