A “Green Card” is evidence of a person’s lawful permanent resident status.
Adjustment of Status
Adjustment of status is the process used when a noncitizen is physically present in the United States and applies for lawful permanent resident status. Adjustment of status saves the noncitizen from having to return to their home country to complete visa processing.
If the noncitizen is already outside of the United States, they may apply at a U.S. Department of State embassy or consulate abroad for an immigrant visa so that they can come to the United States and be admitted as a permanent resident. Additionally, if the noncitizen is inside the US, depending their circumstance, they may need to return to their home country to obtain an immigrant visa and return with the visa before their Green Card will be issued. In both instances, this is referred to as consular processing.
