Countries with permanent residency systems

Permanent Residency (PR) in Australia is similar to the Green Card in USA where a person can retain ones nationality to live and work in the country.

Not every country necessarily has a facility for someone to be a 'permanent resident'. All European Union countries have a facility for someone to become a permanent resident, as EU legislation allows an EU national who moves to another EU country to attain permanent resident status after residing there for five years. Other countries have varying forms of such residency and relationships with other countries with regards to this status.
