Permanent residency and citizenship are not the same things. Permanent residence is a legal status that allows a person to live and work in a country of which they are not a citizen. It typically requires a visa or other authorization from the host country and may involve some form of the residency requirement. On the other hand, citizenship is belonging to a particular nation or state. Citizenship is usually acquired through birth or adoption or can be granted to an individual who has spent a specific amount of time in the country and has contributed towards the economy of that country.
