1. Your soon to be wife can not get a kitas before she gets married with you. If you want to bring her to Indonesia, you could sponsor her on a sosbud visa and later on after you're married convert the sosbud into a kitas. The procedure can be found here http://www.livinginindonesiaforum.or...oreign-husband.
