A residence permit (less commonly residency permit) is a document or card required in some regions, allowing a foreign national to reside in a country for a fixed or indefinite length of time. These may be permits for temporary residency, or permanent residency. The exact rules vary between regions. In some cases (e.g. the UK) a temporary residence permit is required to extend a stay past some threshold, and can be an intermediate step to applying for permanent residency.
Residency status may be granted for a number of reasons and the criteria for acceptance as a resident may change over time. In New Zealand the current range of conditions include being a skilled migrant, a retired parent of a New Zealand National, an investor and a number of others.
