For many derivative citizenship cases, the child must have been a lawful permanent resident and living with the U.S. citizen parent before age 18. If no green card or LPR record exists, the family should verify the history before filing a passport or N-600 claim.
This guide is general information, not legal advice. Families should compare parent naturalization, lawful permanent residence, custody, residence, passport, and N-600 records before relying on any single document.
Parent naturalization alone usually does not make every child a U.S. citizen if the child lacked required status or residence.
A-file, I-130/I-485, old cards, I-90, school, medical, and passport files may reveal whether LPR status existed.
If derivative citizenship is not supportable, the family may need immigration planning rather than a citizenship-proof filing.
Many common derivative-citizenship paths require lawful permanent residence before age 18. The exact rule depends on dates and facts, so the record should be reviewed carefully.
Families can use A-file/FOIA requests, old A-numbers, I-90 records, school records, and parent files to reconstruct the timeline.
Usually the missing LPR issue should be investigated first, because a weak N-600 filing can create a denial record that must be explained later.
