When parents are divorced, separated, or sharing custody, derivative citizenship proof often depends on the exact court order, where the child actually lived, and whether the citizen parent had legal and physical custody before age 18.
This guide is general information, not legal advice. Families should compare divorce orders, parenting plans, school records, residence proof, and the parent naturalization date before filing N-600 or a child passport application.
Legal custody, physical custody, shared parenting, and decision-making language can point to different citizenship proof questions.
School, medical, lease, tax, insurance, and household records can support residence with the citizen parent.
The child must have met the required facts before turning 18; later custody or residence changes may not fix the case.
No. The agency may still ask who had legal custody, where the child lived, and whether all facts existed before age 18.
Yes. School, medical, and household records can help connect the child to the citizen parent’s actual home during the required period.
Usually yes. A custody order can control how the case should be documented and whether extra evidence is needed.
