How to Prove You’re a U.S. Citizen: Documents and Replacements

To prove U.S. citizenship, you need one of five documents: a U.S. birth certificate, a Consular Report of Birth Abroad (CRBA), a Certificate of Naturalization, a Certificate of Citizenship, or a U.S. passport or passport card. Any one of them stands on its own. If you don’t have one, or yours was lost or never issued, each has its own process to obtain or replace, and the right process depends on where you were born and how you became a citizen.

The Five Documents That Count

U.S. birth certificate. A certified copy issued by the city, county, or state where you were born. This is the most common proof for people born in the United States.
Consular Report of Birth Abroad (CRBA). Issued by a U.S. embassy or consulate for children born outside the country to at least one U.S. citizen parent.
Certificate of Naturalization. Given to people who became U.S. citizens through the naturalization process.
Certificate of Citizenship. Issued to people who became citizens automatically through their U.S. citizen parents, without naturalizing.
U.S. passport or passport card. Either version works as standalone proof.

One detail catches people off guard: an expired U.S. passport or passport card still counts as proof of citizenship, provided it was originally issued without limitations.¹ You can’t travel on it, but you can use it when applying for benefits or other documents.

What to Do If You Don’t Have a Primary Document

Unregistered births, records lost to fires or floods, and families that simply didn’t keep paperwork are more common than people expect. Federal regulations allow secondary evidence when a primary document isn’t available.

For a passport application, acceptable secondary evidence includes hospital birth records, baptismal certificates, medical or school records, and other documents created near the time of birth, generally within five years.² Sworn statements from people with personal knowledge of the birth also help. Older, more detailed records carry more weight; a baptismal record from infancy is stronger than one from adolescence.

If your birth was registered late, you likely have what’s called a delayed birth certificate. USCIS scrutinizes these more closely because the fraud risk is higher. A delayed certificate won’t be rejected outright, but an officer will weigh it against your other evidence, so gather supporting records if you’re relying on one.³

Getting a U.S. Birth Certificate

Contact the vital records office in the state where you were born. Every state runs this through its health department, and you can usually apply online, by mail, or in person. You’ll need your full name at birth, date and place of birth, and your parents’ full names as listed on the original record.⁴ Most states also require valid photo ID and proof of a qualifying relationship to the person named on the certificate.

Long-Form vs. Short-Form

States issue two versions: a long-form (the full record) and a short-form or abstract (a summary). To prove citizenship, particularly for a passport, the certificate must list your full name, date and place of birth, your parents’ full names, the registrar’s signature, the filing date (which must be within one year of birth), and the issuing office’s seal or stamp.⁴ A short-form that omits any of these won’t be accepted. When in doubt, order the long-form. Electronic or mobile birth certificates are not accepted for passport applications.

Fees and Timing

Fees for a certified copy generally run from under $10 to around $35 depending on the state. Mail-in requests can take several weeks. Many states offer rush processing or overnight delivery for an extra charge if you need it quickly.

Getting a Consular Report of Birth Abroad

If your child was born abroad and at least one parent was a U.S. citizen at the time of birth, apply for a CRBA through the nearest U.S. embassy or consulate.⁵ A CRBA is issued only for children under 18. After 18, an adult who was a citizen at birth documents that status by applying for a U.S. passport or a Certificate of Citizenship instead.

Physical Presence Requirements

The U.S. citizen parent must meet physical presence requirements in the United States before the child’s birth for citizenship to transfer. When both parents are U.S. citizens, the requirements are relatively light. When only one parent is a citizen, that parent must have lived in the United States for at least five years total before the child’s birth, with at least two of those years after age 14.⁶ Time in U.S. military service, U.S. government employment abroad, or as a dependent of someone in those roles counts. These rules have changed over the decades, so for older births the rules in effect at the time of birth control; births before November 14, 1986 required ten years of physical presence with five after age 14.

Applying

Complete Form DS-2029 and appear in person at the embassy or consulate. Both parents and the child should attend. Bring the child’s foreign birth certificate, proof of the citizen parent’s citizenship, the parents’ marriage certificate if applicable, and evidence of the citizen parent’s physical presence in the United States before the birth. School transcripts, employment records, and tax returns all work as physical presence evidence.⁵ The fee is $100. Processing usually takes several weeks after approval, though it varies by post.

When a Child Is Already a Citizen Automatically

Some children born abroad become U.S. citizens automatically, without naturalizing. Under the Child Citizenship Act, a child born outside the United States becomes a citizen automatically when all three conditions are met before the child turns 18:

At least one parent is a U.S. citizen (by birth or naturalization).
The child has been lawfully admitted to the United States as a permanent resident.
The child is residing in the United States in the legal and physical custody of the citizen parent.⁷

The same rule applies to children adopted by U.S. citizens when the adoption meets the legal requirements for immigration purposes. An exception to the U.S. residency requirement exists for children whose citizen parent is stationed abroad as a government employee or member of the Armed Forces.⁷

Citizenship in these cases happens by operation of law the moment the conditions are met, but it doesn’t come with paperwork. For official documentation, file Form N-600 (Application for Certificate of Citizenship) with USCIS. Filing N-600 doesn’t create citizenship; it recognizes citizenship that already exists and produces a Certificate of Citizenship.⁸ A parent or legal guardian can file for a minor child, and adults who met all conditions before turning 18 can file for themselves.

Replacing a Lost or Damaged Certificate

If your Certificate of Naturalization or Certificate of Citizenship has been lost, stolen, or damaged, file Form N-565 with USCIS online or by mail.⁹ You’ll need your previous certificate number if you have it, the reason for the replacement, and supporting identity documents.

The filing fee is $555 for paper applications or $505 online. There’s no fee if the replacement is needed because USCIS made an error on the original. Fees change periodically, so verify the current amount before filing. Processing can take several months. Applicants who can’t afford the fee may qualify for a waiver using Form I-912.¹⁰

Name Changes

Form N-565 also handles name updates. If your name changed after naturalization through marriage, divorce, or a court order, you can request a new Certificate of Naturalization in your current legal name. USCIS will update the name only if the change happened after the naturalization date, and you’ll need to submit the original certificate along with a certified copy of the marriage certificate, divorce decree, or court order.¹¹

Amending a CRBA

Correcting or amending a CRBA goes through the State Department, not USCIS. Submit a notarized Form DS-5542 with the original CRBA, a photocopy of your valid photo ID, and original or certified documents supporting the change. The fee is $50 per record, payable by check or money order to the U.S. Department of State.¹² Processing takes four to eight weeks. CRBAs issued before November 1, 1990 may require a manual search at the National Archives that adds another 14 to 16 weeks.

Proving Citizenship to an Employer

Every U.S. employer verifies identity and work authorization using Form I-9. A single document from “List A” satisfies both. The List A documents that work include a U.S. passport or passport card. (A Permanent Resident Card is also on List A but establishes lawful permanent residence, not citizenship.)¹³

If you don’t have a passport or passport card, present one identity document from List B (such as a driver’s license) and one work authorization document from List C (such as a birth certificate or Certificate of Naturalization). A certified copy of the birth certificate works; you don’t need to hand over the original. Your employer cannot tell you which documents to present or refuse a valid one because they’d prefer something else.
