Bureaucratic procedures exist in every country for setting up in a new location. And those moving to the state capital of Düsseldorf will find that Germany is no exception. The rules here are on the whole rather clear but being somewhat complicated, not so easy to follow.
In general, anyone who plans to remain here for more than three months will need to register with the local authorities, ideally within the first week after arrival. Everything then depends much on country of birth and nationality.
One great achievement of the EU and its institutions is that most of its 500 million inhabitants can relocate across borders relatively easily. The Residence Act (Aufenthaltsrecht) is a complex paper, which reveals most answers for all the global nationalities. Freedom of movement in the EU exists but has strict rules.
The process of registration in Düsseldorf is straightforward though. A short trip to the Einwohnermeldeamt or the local Bürgerbüro with the registration form completed with necessary details and a valid passport or official ID.
