You can file for diorce in Pennsylvannia so long as you meet the residency requirements.  The issue will be having him served in Jordan and for that you should seek help from an attorney in your area.  The Court may need to order how service is made since most states require personal service of the divorce papers.  Also, he can not stop you from getting a divorce under the state's no-fault laws.  A stumbling block could also be if you won anything together.  Good luck.
