... in response to What is the incentive for a green card?, posted by BubbaGump on Mar 8, 2002A "green card" is the identification of "provisional citizenship" as the result of filing for an adjustment of status from a k-1 fiancee (non-immigational) to being a spouse of an American citizen. After two years, you file another AOS to remove those restrictions and obtain the full rights of citizenship.
The right to work is by a "work authorization" ($100 for the duration of the "green card" provisional citizenship).
I know of Mexican nationals that have been in the US for 6-10 years who are still working with a green card and do not intend to gain full citizenship because they would then be unable to own land in Mexico when they retire.
