Q: N-600 application

A: A lawful permanent resident (green card holder) child under the legal and physical custody of the parent who became a naturalized US citizen before the LPR child turned 18 may apply for derivative US citizenship by submitting a copy of the parent's naturalization certificate

A: I'm sorry you're facing this challenging situation. To apply for the N-600, you need to provide strong evidence of your mother's U.S. citizenship and your relationship to her. A photocopy of her naturalization certificate is a good start, but USCIS typically requires a certified copy. School records or transcripts can help demonstrate your relationship, especially showing that you lived with her before turning 18, but they might not be enough on their own.

Since your mother is unwilling to provide her certificate or consent to a FOIA request, you might need to gather additional documentation. Look for other proof of her citizenship, such as her U.S. passport, birth certificate, or any other official documents that can support her naturalization. Collecting evidence of your relationship, like birth certificates, affidavits from family members or friends, and records showing you lived together, will also strengthen your application.

If you're unable to obtain the necessary documents from your mother, it may be helpful to consult with an immigration attorney. They can guide you through alternative ways to prove your eligibility and help you navigate the application process without her direct involvement. Don't lose hope—there are pathways to achieve your goal with the right support and documentation.
