Certificate of Citizenship

A Certificate of Citizenship, issued by U.S. Citizenship and Immigration Services on Form N-560, proves that someone acquired or derived U.S. citizenship through a parent rather than by naturalizing themselves. It is evidence of status, not a travel document, and it does not expire.

Form numbers N-560 (original), N-561 (replacement)
Issuing authority U.S. Citizenship and Immigration Services (USCIS)
Applied for using Form N-600, Application for Certificate of Citizenship
Issued to People who acquired citizenship at birth abroad to a U.S. citizen parent, or derived it when a parent naturalized before their 18th birthday
Not issued to People who naturalized themselves — they receive Form N-550
Expiry None
Travel use Not a travel document
Form I-9 status Acceptable List C document, establishing employment authorization
Machine-readable data None — no MRZ, no barcode, no chip

How it works

Two routes lead to a Certificate of Citizenship, and they produce identical documents from very different facts.

Acquisition happens at birth. A child born outside the United States to at least one U.S. citizen parent may be a citizen from birth, subject to conditions on that parent’s prior physical presence. Nothing is granted — the citizenship already existed.

Derivation happens later. A lawful permanent resident child automatically becomes a citizen when a parent naturalizes, provided the child is under 18, holds a green card, and is in that parent’s legal and physical custody. Again the status transfers by operation of law.

In both cases the holder files Form N-600 to request the certificate, sometimes decades after the qualifying event. That lag creates a practical problem for anyone verifying one: a certificate issued in 1984 and one issued last year are both valid and look nothing alike. USCIS has revised the design and its security features repeatedly. An older design is not a suspect design.

Why it matters for identity verification

Certificates surface in employment eligibility checks, financial onboarding, benefits enrollment, and passport applications. In each the document does something a driver’s license cannot: it attests to legal status, not identity alone.

That makes it valuable to forge and awkward to verify. It carries no machine-readable zone, no barcode, and no chip, so none of the automated cross-checks that make a passport tractable are available. There is no encoded copy of the printed data to check the printed data against. Everything is read optically and judged against a template — and the right template depends on an issue date that may predate the reviewer.

Remote capture compounds this. A phone camera resolves print quality and the raised seal reasonably well in good light, but the certificate’s security depends partly on substrate characteristics a single flat image does not convey. This is a document where automated document authentication narrows the field rather than closing it, and where pairing the document check with a biometric comparison does more work than scrutinizing the certificate alone.

Certificate of Citizenship vs Certificate of Naturalization

  Certificate of Citizenship Certificate of Naturalization
Form number N-560 / N-561 N-550 / N-570
How citizenship was obtained Acquired at birth abroad, or derived through a parent’s naturalization Granted after the holder completed the naturalization process
Age at the qualifying event Under 18 18 or older
Application form N-600 N-400
Oath of allegiance Not required Required

Both prove citizenship and both are acceptable for employment verification. They answer different questions about how the holder became a citizen — which matters when the reason for asking is regulatory.

What it can’t do

It is not a travel document. The certificate establishes status but grants no right of entry and is not accepted at a border in place of a passport. Holders who travel internationally still need one, and the certificate is often the evidence used to get it.

It offers no machine-readable cross-check. A passport’s machine-readable zone and a driver’s license barcode both duplicate the printed data, so a mismatch exposes tampering instantly. The certificate has no such redundancy. Alter the printed name and nothing contradicts it.

Its design varies by decade, which defeats naive template matching. Systems expecting one canonical layout reject valid older certificates, and may accept forgeries modeled on a design they know poorly. Coverage across issue eras is the constraint, not accuracy on any single design.

It proves status, never presence. The certificate says a named person is a citizen. It carries a photograph, but confirming the person submitting it is that person is a separate check the document cannot perform alone.

Frequently asked questions

Does a Certificate of Citizenship expire?

No. It carries no expiration date and remains valid indefinitely, including versions issued decades ago. A replacement is needed only if the certificate is lost, stolen, damaged, or the holder’s name has legally changed.

Can I use a Certificate of Citizenship instead of a passport?

Not for travel. Border officials will not accept it in place of a passport. It is commonly used as supporting evidence when applying for one.

Is a Certificate of Citizenship valid for Form I-9?

Yes. Forms N-560 and N-561 are acceptable List C documents, establishing employment authorization. A List B document establishing identity is still required alongside it.

Why do Certificates of Citizenship look so different from each other?

USCIS and its predecessor have redesigned it several times, adding data elements and security features each revision. Because holders often apply years after becoming citizens, multiple designs circulate at once. An older layout missing newer features is not evidence of forgery.
