Does My Child Automatically Become a U.S. Citizen If I Naturalize?
Many parents are surprised to learn their child may already be a citizen, or about to become one, without a separate application. Here's the general picture.
Automatic citizenship through a naturalizing parent
Under current rules, a child generally acquires citizenship automatically when at least one parent naturalizes, if the child is under 18, is a permanent resident, and is living in the U.S. in that parent's legal and physical custody at the time.
When a separate application is still needed
If your child doesn't meet all of those conditions, for example if they're living outside the U.S. at the time, you may need to file a separate application to document or establish their citizenship rather than relying on automatic acquisition.
Children born abroad to a U.S. citizen parent
Separately, a child born outside the U.S. to a parent who is already a U.S. citizen at the time of birth may acquire citizenship directly at birth, depending on the citizen parent's own history of physical presence in the U.S. This is a different, and often more complex, set of rules than automatic acquisition through a naturalizing parent.
