How many years do I have to live in the United States to get a green card?

A green card is a permanent residence permit for foreign citizens. Holding a green card means that the cardholder has the permanent residence in the issuing country, and at the same time, holding a green card can exempt entry visas for a certain period of time. The official title of green card in the United States is "permanent resident card", also called I-55 1, which records the cardholder's photo, fingerprint, name and other information and can be obtained through application. Applicants usually need to have a permanent job in the United States or their spouses and children settle in the United States. If the application is successful, the green card will be issued to the applicant, and the cardholder needs to update the card on schedule.

The word green card originated in the United States, because the earliest permanent residence permit in the United States was a green card. With the change of design, 20 versions were updated, but the name of green card was retained. In May of 20 10, the green card turned green again, and a yellow-green pattern was added to the previous white background. Other countries follow the United States and call their permanent residence permits green cards.
