Green card, permanent residence, temporary residence and changing nationality are all stupid? How to distinguish

The word "green card" is actually "permanent residence", especially in the United States.

Because the documents issued by the US government to permanent residents are green, China people are used to calling the right of abode in the United States a "green card"; "permanent residence"

As the name implies, foreign citizens have the right to stay permanently in the local area.

Obtaining "permanent residency" also means that you can live permanently in the country and enjoy the same treatment as its citizens in many aspects. Temporary residence is one of the stages leading to permanent residence or nationality. Generally speaking, after obtaining the "temporary residency", you can obtain the "permanent residency" (PR) through certain conditions. Finally, on this basis, after completing certain conditions, you can obtain the nationality of the country and change it into a passport.
