Can children born in the United States who have expired obtain American citizenship?

Born in the United States

If you were born in the United States, you will acquire American citizenship at birth (except for the children of diplomats). A birth certificate is a proof of citizenship.

Born outside the United States

If you were born outside the United States and at least one of your parents is an American citizen. Then as long as parents meet certain conditions, they are born American citizens.

Permanent residents of the United States can obtain citizenship in the following ways:

My spouse is an American citizen, and I have met the residence requirements for three years and applied for naturalization.

If a permanent resident gets a green card for marrying an American citizen, he can get American citizenship faster than ordinary permanent residents. Specifically, after obtaining a green card, the spouse of an American citizen can become an American citizen by submitting an N-400 naturalization application as long as he has lived in the United States continuously for at least 3 years and actually lived for at least 15 months, and meets other naturalization requirements.

Meet the five-year residence requirement and apply for naturalization.

If a permanent resident does not get a green card because he is married to an American citizen, he can apply for naturalization as an American citizen by submitting the N-400 form as long as certain conditions are met. These conditions mainly include: continuous residence in the United States for at least 5 years, actual residence for at least 30 months, and good conduct.

The spouse is an American citizen and works outside the United States.

If a permanent resident gets a green card because he is married to an American citizen, and the American citizen works overseas, then the permanent resident may become an American citizen in a short time by submitting an N-400 application. Such permanent residents do not need to be restricted by continuous residence time and actual residence time. As long as certain conditions are met, they can apply for naturalization immediately after obtaining a green card.

Military service personnel naturalized as American citizens.

Permanent residents who have served or served in the US military can be naturalized as American citizens as long as they meet certain conditions. These permanent residents are not limited by continuous residence time, actual residence time and residence time in the state, so naturalization is relatively simple. In addition, they do not need to pay any fees for applying for naturalization or obtaining a naturalization certificate.

Both parents are American citizens. According to American immigration law, if both parents are American citizens, their children can automatically acquire American citizenship.

Only one of the parents is an American citizen. According to American immigration law, this American citizen must live in the United States for more than 5 years before his/her child is born, and must live in the United States for at least 2 years after 14.

In order to prove that they meet this requirement of immigration law, the parents of American citizens are obliged to provide relevant documents, which can be passport certificates for entry and exit, certificates from the entry and exit administration, transcripts of American schools, letters from employers, lease certificates, payment receipts, tax bills, historical letters, etc.
