Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.
The global population of immigrants has grown since 1990 but has remained constant at around 3% of the world's population.

The Iron Curtain in Europe was designed as a means of preventing emigration. "It is one of the ironies of post-war European history that, once the freedom to travel for Europeans living under communist regimes, which had long been demanded by the West, was finally granted in 1989/90, travel was very soon afterwards made much more difficult by the West itself, and new barriers were erected to replace the Iron Curtain." —Anita Böcker
Permanent residency is a person's legal resident status in a country or territory of which such person is not a citizen but where they have the right to reside on a permanent basis. This is usually for a permanent period; a person with such legal status is known as a permanent resident. In the United States, such a person is referred to as a green card holder but more formally as a Lawful Permanent Resident (LPR).
