When you become a permanent resident, you receive a green card. The green card is similar in size and shape to a credit card. Newer green cards are machine-readable. The face of a green card shows information such as name, alien registration number, country of birth, birth date, resident date, fingerprint, and photo. Lawful permanent residents or "green card holders" must carry their green card with them at all times. From USCIS: "Every alien, eighteen years of age and over, shall at all times carry with him and have in his personal possession any certificate of alien registration or alien registration receipt card issued to him. Any alien who fails to comply with [these] provisions shall be guilty of a misdemeanor." In years past, the green card was green in color, but in more recent years, the green card has been issued in a variety of colors, including pink and pink-and-blue. Regardless of its color, it is still referred to as a "green card."

Also Known As: The green card is known as "Form I-551." Green cards are also referred to as a "certificate of alien registration" or "alien registration card." Common Misspellings: The green card is sometimes misspelled as greencard. Examples: "I passed my adjustment of status interview and was told that I would receive my green card in the mail." Note: The term "green card" can also refer to a person's immigration status and not just the document. For example, the question "Did you get your green card?" could be a question about a person's immigration status or the physical document.
