How long can an American green card stay in China every year?

The longest time that an American green card can stay in China every year is half a year. Green card holders can't leave the United States for more than six months at a time. If they don't return after an extension, their green cards may be cancelled. There is a way to apply for permanent residence in China. You can leave the United States for two years by applying for re-entry permit.

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 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.
