How long does it take for an American green card to apply for American citizenship?

1. The father has an American green card and applied for an American green card for his 0-year-old son.

If the child is born in the United States, he is directly an American citizen.

If the child is born in China, the timetable for the green card for minor children is a little over two years.

2. The father became an American citizen and applied for American citizenship for his son (with an American green card and living in the United States for less than five years) aged 17.

In this case, the child will automatically become an American citizen at the moment when his father is naturalized, and there is no need to apply separately.
