How long can I get a green card when I get married in America?

The country can get a green card after two years of marriage.

There are two main types of green cards that can be obtained after marriage in the United States: temporary green cards valid for 2 years and permanent green cards valid for 10 years. Married for 2 years or more, you can apply for a permanent green card. If your spouse is an American citizen, you will get a temporary green card for two years if you apply for marriage immigration, and a permanent green card if you get married for two years or more.
