Does the U.S. law require that a mother’s children become American citizens?

According to U.S. law, a child can directly become a U.S. citizen as soon as he or she is born in the United States (including airspace) (you can also choose not to join). Regardless of whether the parents are U.S. citizens.

If one of the parents has American citizenship and has lived in the United States for more than five years, his or her children between the ages of 16 and 18 must apply for naturalization independently.
