Since you have been living in Pennsylvania for seven years and your wife has been there for six years, Pennsylvania should have jurisdiction over your divorce proceedings. Most states do not require citizenship or permanent residency to have authority over divorce matters, as long as you satisfy the residency requirements of the state, which is determined by time living in the state. Concerning the specific Pennsylvania state residency requirements, it would be best for two consults with an experienced attorney-mediator in Pennsylvania who can provide you with detailed counsel.
