How long does it take to get a green card after receiving EAD card?

A green card, that is, a permanent residence permit for foreigners, 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 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.
