A FOIA request for a child can reveal information useful for adoption cases and for cases regarding US citizenship obtainment.
If you are a parent or legal guardian submitting Form G-639 on behalf of a child, you must establish your own identity as the child’s parent or legal guardian. You will have to provide one of the following documents: the child’s birth certificate, adoption decree or other official document proving your relationship to the child. Herewith, the signature of the parent/guardian on Form G-639, Freedom of Information Act/Privacy Act Request, must be signed under penalty of perjury or notarized.
