Is Korea an immigrant country now? Does it have a green card? Is it Korean nationality after getting a green card? How can I get a green card? Please help me.

A green card is not a nationality. Even if you get a green card, you still have your original nationality, but you can travel freely within the validity period. A green card is also called a permanent residence permit, allowing you to stay and work.

As for the green card application in South Korea, it seems that the policy changes slightly every time the president changes. It is easier to apply if a relative in the family has already become a citizen, as long as the kinship is proved, DNA identification is done or something, and a certain bank guarantee is required.

If you want to become a citizen, you have to pass the language, history and other exams.
