What is the I-551 document also known as?

The I-551 document is officially referred to as the Permanent Resident Card, more commonly known as the Green Card. This card serves as proof of an individual's status as a lawful permanent resident of the United States. It allows holders to live and work in the U.S. on a permanent basis and is essential for those who wish to establish long-term residency.

The designation as a "Permanent Alien Resident Card" reflects its purpose in documenting an individual's immigration status, which is distinct from other types of documents such as employment authorization cards or temporary protection status documents. Each of those other options serves different functions within the immigration system. For instance, an employment authorization card is temporary and allows individuals to work legally in the U.S., while a temporary protected status card is issued to individuals from designated countries experiencing ongoing conflicts or natural disasters. A visa card, on the other hand, refers to a document that allows entry into the U.S. for a specific time and purpose but does not indicate permanent residency. Thus, the term "Permanent Alien Resident Card" accurately captures the essential nature of the I-551 document and its significance in the realm of U.S. immigration.
