US Naturalization Certificate
Apostille for Use in India
For Indian-origin US citizens, the Certificate of Naturalization is the document that proves when US citizenship was acquired — which is exactly what OCI applications, renunciation of Indian citizenship, and PAN/property matters in India need to see. It's a federal document, apostilled only by the US Department of State in Washington, DC — the same office we visit for FBI PCCs, which makes this squarely our specialty. And there is one rule that catches almost everyone: you cannot apostille the original, and you must not notarize or photocopy it.

Your child's US birth certificate takes a different route entirely
A naturalization certificate is federal and goes to Washington DC. A birth certificate is a state vital record and goes to the issuing state's Secretary of State — Sacramento, Austin, Trenton. Same OCI application, two different offices, two different timelines. We run both chains in parallel from one shipment.

Competent Authority
US Department of State, Washington, DC
The naturalization certificate is issued by USCIS, a federal agency — so its apostille comes exclusively from the US Department of State's Office of Authentications in Washington, DC. No state office can touch it, and no notary can certify it. What the State Department authenticates is a USCIS-issued certified true copy, not your original certificate: federal law prohibits attaching an apostille to the original identity document. Once the Office of Authentications has the correct copy, turnaround is on the order of a few business days plus the mail queue — and we submit in person at the counter, the same walk-in route that keeps our FBI PCC timelines short.
What You Need Before We Start
A USCIS-issued certified true copy of the Certificate of Naturalization. This is the document that gets apostilled — obtained through the USCIS authenticated-copy process, or via Form N-565 where a replacement certificate is needed.
Not the original itself, and never a notarized photocopy. Federal law restricts attaching an apostille to the original USCIS identity document, and a notary has no authority to certify a federal record — submitting either gets the request rejected. Message us before you have anything notarized.
Your destination requirement if you have it (OCI checklist, consulate letter) so we confirm the apostille is what's actually needed.

Where an Apostilled US Naturalization Certificate Is Required
OCI applications
The OCI application for naturalized US citizens of Indian origin turns on the naturalization certificate — it establishes the date citizenship was acquired, and filings from India need it apostilled.
Renunciation of Indian citizenship
The renunciation process examines when you became a US citizen; consulates and VFS ask for the authenticated certificate in many case types.
Property, PAN & inheritance in India
Indian banks, sub-registrars, and tax authorities handling a US citizen's Indian assets frequently require the apostilled proof of citizenship status.
What It Costs
Because this is the same federal route as our FBI PCC service, our flat plans apply: Economy $175 (about 3–4 weeks), Standard $225 (about 2–3 weeks), Express $325 (about 1–2 weeks, same-business-day State Department submission with a free scanned copy). Return shipping options to India quoted upfront.
