In what year was the first green card introduced?

The introduction of the first green card occurred in 1950. This period marked significant changes in U.S. immigration policy, particularly with the Immigration and Nationality Act of 1952, which established a more structured system for the admission of immigrants. The green card itself became an emblem of lawful permanent residency, providing holders with the right to live and work in the United States permanently.

The choice from 1950 reflects historical context, as prior to its introduction, various forms of documentation were used for immigrants, lacking the standardized nature that a green card would later provide. This card not only facilitated the tracking of immigrants but also solidified the concept of permanent residency, as it was issued specifically to individuals who were granted status in the U.S.

In contrast, options from 1940, 1960, and 1970 do not align with the historical timeline of the green card's introduction. By 1960, the concept had evolved, and by 1970, there were further updates to immigration policies and card design. Thus, the year 1950 captures the critical moment when the green card system was initiated.
