Same, different names. . . The United States is called green card, Canada is called maple leaf card, and so on. . .

PR = permanent resident. If you insist, refugees from some countries can also give you PR status and live permanently, but you didn't move here as an immigrant, but through refugee channels. In this case, some countries will treat it differently. . .
