There is a "Swear-In" ceremony, from what seems to be about once a month or so, in which imPorts are encouraged to go to and "pledge allegiance" to the government. The benefits of registering include free housing, free medical benefits, job security, and a legal allowance to be a "hero" without constant explicit permission from the government. It also allows for frequent and easy access to the Porter, amongst other things.

Failing to "register" puts you at an "unsettled" status, and overall makes your life more complicated here. On purpose, I would think, so that you will be more likely to register. Many imPorts don't register, due to the fear of "owing" the government in some manner. I am certain the Count has his own feelings on the matter.
