The right to free movement of persons is the right to move and reside freely in any place within a particular region. An example implementation of this right is the European Union's policy of allowing all EU citizens and their family members to move and reside freely within all EU member states, with the following conditions:
1. EU citizens can live in another EU country for up to three months without any requirements other than holding a valid identity card or passport.
2. In order to stay in another EU country for more than three months, EU citizens have to meet certain conditions depending on their status (for example worker, self-employed, student, etc.) and may be asked to comply with administrative formalities.
3. EU citizens have the right of permanent residence in another EU country after legally residing there continuously for five years.
4. Family members of EU citizens, either EU citizens or nationals of a non-EU country, have the right to accompany or join EU citizens. They may be asked to comply with certain conditions or formalities.
