How does it work in Germany, Walter?
In order to vote in an election, it is necessary to be registered in an electoral register or in possession of a voting certificate.
Now, normally, you are automatically registered (for voting) in the community (city, town, village) where you live (because you have to register at the "registration of address office"). The electoral office of this community sends you the certificate a couple of weeks before the actual election.
If you can't vote in your polling station, you either ask for postal vote or for a certificate to vote in another polling station. (The last is somewhat limited, regarding if there are community, county, state elections.)
