What this form does
Documents citizenship for someone who is already a citizen through a parent, rather than granting it. Median runs about 9 to 11 months for the certificate to arrive.
What affects the timing
Evidence of the parent's citizenship and the legal relationship is what gets reviewed. Because it confirms an existing status, an applicant can often travel on a US passport while it is pending.
