Yes, in some cases you may acquire or derive U.S. citizenship through your parents, depending on your age, your parents' status, and your residency.

You might already be a citizen if at least one parent was a U.S. citizen at your birth and met residency requirements.

If you're a green card holder under 18 and your parent naturalizes, you may automatically become a U.S. citizen.

If you believe you already acquired citizenship through your parents, you can apply for a Certificate of Citizenship with Form N-600.
