Just to make sure you don't misunderstand. In NJ you need a firearms I.D card to purchase firearms. I don't recall the exact meaning, look it up yourself at NRA state info site, but if you should move to New jersey and not have the card yet, I think you may still keep the guns as long as you know you would qualify for a card and are in process of getting I.D card. It is not the same as NYC in that you DO NOT have to register firearms in NJ. You don't need permit for each gun etc. If you were to have your F.I.D card you will not have to take each gun or register each gun with the police. You don't have to tell them anything about your guns. They only thing the card is used for is to purchase firearms, not as a license for possession in your home(again check laws) like NYC. I believe in NYC they require you to register each gun and pay a fee for each individual firearm, but you probably know. Welcome to NJ.
