Can I apply for a green card for my child when I marry an American?

1. If your child is an American citizen at birth, then the child can obtain American citizenship no matter where he was born, but the American citizen must have lived in the United States for five years, two of which are after reaching the age of 14. Even if American citizens were born in the United States, they still need to provide proof of their residence time in the United States. Just have a residence in the United States, register as a voter, etc. Not enough to prove the time of living in America.

2. Children of non-American citizens who are under 18 years old when they are married to American citizens can apply for CR2/IR2 visas for their children before they are under 2 1 year old, and they can get green cards directly after entering the United States;

3. If the child 18 years old but under 2 1 years old, and you are not married to an American citizen, an American citizen can apply for a K 1 (fiancee visa of an American citizen) with your child's K2 visa, get married within 90 days after you enter the United States, and then apply for a green card for you and your child;

4. Children over 2 1 year old can only apply for an immigrant visa after getting a green card, and then get a green card.
