A permanent resident is a non-US Citizen authorized to live and work permanently in the United States. Obtaining permanent residency is commonly referred to as receiving a green card.  For a long time this was a misnomer as a “green card” was not actually green, but now the newly redesigned permanent residency card is once again actually green. In addition to a “green card holder” a permanent resident may also be referred to as a: “lawful permanent resident”, “legal permanent resident”, or “permanent resident alien”. There are several ways to obtain permanent residency, most commonly through one’s employer or through a family member. A certain number of people also obtain permanent residency each year through the visa lottery. While permanent residents can live and work in the United States permanently, a permanent may still lose his or her green card. For example, a foreign national that remains abroad for over a year without obtaining a re-entry permit may shockingly lose his or her permanent residency upon attempted re-entry. The government can also take away someone’s green card if convicted of certain crimes. However, once someone becomes a citizen it is virtually impossible to lose citizenship without intending to do so. This is one of the many advantages to becoming a U.S. Cititizen.
