Adjustment of Status or getting a "Green Card", is the process when someone who is not a citizen of the United States, applies for and is granted permission to live and work in the United States permanently. Adjustment of Status is for those who are physically present in the United States when they apply. Those outside the United States must apply through the consulate.
A simple application takes seven to nine forms to be completed. And according to the Office of Management and Budget of the White House, it takes a little over 21 hours and a half hours to complete the forms and gather the supporting documents.
