What is the use of a US green card?

Lawful permanent residence for green card holders is an official grant of immigration benefits, including conditional permission to remain and work in the United States.

1. Enjoy the benefits stipulated by the US government; (for example: each family member can freely enter and exit the United States at any time and live in the United States)

Generation background

The official name of the green card is "Permanent Resident Card" (Form I-551). The name "Green Card" comes from its predecessor, the Alien Registration Receipt Card (Form I-551) introduced at the end of World War II. Form I-551 was adopted in 1977 and has been printed on various colors of paper, except green.

But despite this, the name "green card" is still used. As of January 2008, the main color of the card was yellow and white, with only the text on the back using green. A green card contains the name, photo and other information of its holder. In recent decades, with the development of technology, green cards have also added many anti-counterfeiting features.
