American citizenship conditions If a baby is born in the United States, he can acquire the citizenship of that country. Can his parents' nationality be changed?

Babies born in the United States can become American citizens after 18 years old, and their parents' nationality remains unchanged. However, children can apply for parents' immigration when they are adults, and parents can also become American citizens after they meet certain living conditions. The following is the relevant legal support:

The 14 amendment to the US Constitution stipulates that anyone born in the United States will automatically acquire American citizenship. This is what we know as American landing citizenship.

American citizens over 2 1 year-old or over 2 1 year-old have the legal qualification to apply for permanent residence and stay in the United States, that is, they have the right to work and live in the United States indefinitely.

The meaning of parents in American immigration law includes: biological parents, stepparents and adoptive parents. However, if an American citizen obtains citizenship through legal adoption, he no longer has the right to apply for the permanent residence of his biological parents in the United States.

Because the parents of American citizens are immediate family members, American immigration law stipulates that there is no limit on the number of immigrant visas for parents of American citizens to apply for green cards.
