Rahway doesn't do Registration, they only do Licenses and Testing and I didn't have an appointment when I went. Today, they're only seeing a total of 120 Customers daily. You have to come early like I did (3:30 AM) to place a folding chair to hold your spot or just stand in line if you wish. Once the doors opened, the line moved pretty fast and it's well organized. Make sure you have all your documents, you won't be allowed back in once you're out of the building. Good luck!
If this is the first time that you are registering it you have to make an appointment, if it's already registered then you can go online and renew the registration.
