An immigrant may obtain various forms of identification after processing, with the Alien Registration Card being a significant one. This card serves as proof of a person's legal status in the country and is essential for immigrants as it confirms their eligibility to live and work in the United States. The Alien Registration Card, commonly known as a Green Card, provides important benefits, including the ability to travel in and out of the country, the right to work legally, and access to certain social services.

Although other options like a driver's license, social security card, and state identification card may also be available to immigrants, these cards are typically issued under different circumstances. For instance, a driver's license requires proof of residency and may vary by state, while a social security card is associated with an individual's work eligibility and is usually issued after obtaining an Alien Registration Card. The state identification card, often similar to a driver's license, also depends on state regulations about the issuing process, which typically requires some form of legal status. Thus, the Alien Registration Card is the primary document specifically tied to immigrants' legal status and their rights in the United States.
