What is a green card? What are the requirements for its use?

1. Conditional green card, which is a two-year conditional green card that is obtained after a foreigner marries a citizen. After two years, if the conditions are met, it can be converted into a formal green card.

2. Temporary green card. Investment immigrants get a two-year temporary green card. After two years of successful investment, it can be converted into a formal green card.

3. The official green card is renewed every ten years.

Usage Requirements

According to U.S. Citizenship and Immigration Laws, green card holders are foreigners who do not have U.S. nationality or U.S. citizenship. However, they basically enjoy the same treatment as nationals of their own country in the United States, but they do not have the right to vote or be elected.

According to U.S. immigration laws, permanent residents must use a valid immigrant visa and a valid passport from their home country when entering the United States, otherwise they will not be allowed to enter. After you have a U.S. green card, as long as you leave the United States for less than one year, the green card itself can be used as a valid entry immigration visa. There is no need to apply for a separate visa at the U.S. embassy or consulate.

If you leave the United States for more than one year, you must apply for a return visa as a valid immigrant visa for entry before leaving the country. The return visa is valid for up to two years. Card holders who have not entered the United States for more than a period of time are likely to be judged to lose their permanent residency when they enter the country, because immigration law requires green card holders to leave the United States temporarily.
