Some people become U.S. citizens through a parent at birth or during childhood without going through naturalization themselves. Form N-600 is one way eligible individuals can ask USCIS for a Certificate of Citizenship documenting that status.
Whether citizenship was acquired or derived depends on facts such as your birth, your parents’ citizenship and residence history, and sometimes your age and immigration status. E-Z Immigration can help review your family timeline, identify relevant records, and prepare an N-600 application when appropriate.
An application for a USCIS Certificate of Citizenship documenting citizenship acquired or derived through a parent.
Certificate of Citizenship Explained
Form N-600, Application for Certificate of Citizenship, is used to ask USCIS for a certificate documenting U.S. citizenship. It is generally for people who already became citizens through a U.S. citizen parent and want official documentation of that status.
The evidence needed depends on how and when citizenship was acquired or derived. Relevant details may include the applicant’s birth, parent-child relationship, a parent’s citizenship and residence history, and, for some claims, the applicant’s age and immigration status.
Some people may have other evidence of citizenship, such as a U.S. passport or a Consular Report of Birth Abroad. Which document is available or appropriate depends on the facts and the purpose for which proof is needed.
Form N-600 does not itself make someone a U.S. citizen. An applicant must already have acquired or derived citizenship under the law that applies to their circumstances and provide evidence supporting the claim.
Two Paths Through a Parent
The terms describe different ways a person may have become a U.S. citizen through a parent. The relevant requirements depend on the law in effect and the details of the family and immigration history.
Acquired citizenship generally refers to citizenship obtained at birth through a U.S. citizen parent, even when the child was born outside the United States.
The requirements may depend on the law in effect on the person’s birth date, the parent’s U.S. citizenship and physical presence in the United States, and the parent-child relationship.
Key timeline: the child’s birth and the parent’s history before it.
Derived citizenship generally refers to a child who automatically became a U.S. citizen after birth when a parent became a U.S. citizen, if the applicable legal requirements were met.
Depending on the claim, relevant facts may include the child’s age, lawful permanent resident status, and residence in the legal and physical custody of the U.S. citizen parent.
Key timeline: the child’s age and status when the parent became a citizen.
The rules are not the same for everyone. The applicable law may depend on the date and circumstances of birth, adoption, parents’ marital status, and other details. Reviewing the timeline and supporting records can help identify which requirements may apply.
The application may document citizenship a person already acquired or derived through a qualifying parent.
N-600 Eligibility
Form N-600 may be appropriate for someone who claims to have acquired or derived U.S. citizenship through a qualifying parent and can document that claim.
The correct applicant and eligibility requirements depend on the basis for the citizenship claim. In some circumstances, a U.S. citizen parent or legal guardian may file for a minor child. Current USCIS instructions explain who may file and how to submit an application.
Evidence requirements vary. Older records or differences in names and dates may call for additional documents or an explanation. Eligibility depends on the facts and the law that applies to the individual claim.
N-600 Application Support
Citizenship claims through a parent can depend on family events and records from many years ago. We help individuals and families organize the relevant history and understand the application steps for their circumstances.
Review birth and family history to identify whether an acquired or derived citizenship claim may apply and which legal requirements may be relevant.
Identify records that may connect the applicant to the U.S. citizen parent, such as birth or adoption records, parentage evidence, marriage records, or custody documents.
Review available records showing a parent’s U.S. citizenship, which may include a U.S. birth certificate, naturalization certificate, Certificate of Citizenship, or other official documentation.
For claims where these details matter, organize the child’s age, permanent residence, and residence in the parent’s legal and physical custody into a clear timeline.
Prepare the application, check that information is complete and consistent, and identify gaps or differences in supporting documents that may need attention.
If USCIS requests evidence, schedules biometrics, or sets an interview, review the notice to understand what it requests and the next steps or response deadline.
The specific services and evidence review depend on the citizenship claim, available records, and the engagement.
Build the Supporting Record
The records needed depend on the citizenship claim and the applicant’s history. Depending on the circumstances, evidence may include documents such as:
The applicant’s birth certificate and, when relevant, adoption or parentage records.
Evidence of the U.S. citizen parent’s citizenship.
The applicant’s Permanent Resident Card or immigration records, if relevant.
Parents’ marriage, divorce, or custody documents, when relevant.
Evidence of the parent’s U.S. residence or physical presence before the applicant’s birth, if required for the claim.
Records showing the child’s residence and legal or physical custody, when relevant.
Certified translations for documents that are not in English.
This is a general list, not a universal checklist. USCIS evidence requirements depend on the legal basis and the applicant’s history. Unavailable or inconsistent records, or records issued under different names, may call for additional explanation or alternative evidence. Review current USCIS instructions for the specific application.
From Claim Review to USCIS Decision
The steps generally involve identifying the basis for the citizenship claim, gathering records that support it, and responding to USCIS notices. The process and evidence can vary by case.
Identify whether the claim is based on citizenship at birth or citizenship acquired through a parent after birth. The timeline helps determine which requirements may apply.
Collect documents establishing identity, parentage, the parent’s citizenship, and relevant residence, custody, or immigration facts. Request missing records when possible.
Complete the current form and submit it with the required evidence and fee, unless a fee exemption applies. Follow the latest USCIS filing and payment instructions.
USCIS may reuse biometrics, schedule an appointment or interview, or request more evidence. Follow the instructions and deadlines in each notice.
USCIS reviews the application and evidence to decide whether the applicant qualifies for a Certificate of Citizenship. The decision notice explains the result and any applicable next steps.
Follow each USCIS notice carefully. Filing steps, evidence requests, appointments, and timelines depend on the case. Check current USCIS instructions and processing information.
Organized, Case-Specific Support
An N-600 claim can depend on family records and events from many years ago. Missing documents, differences in names or dates, or questions about custody or residence can make the history difficult to present.
E-Z Immigration helps clients organize that history and understand which records may support the citizenship claim, prepare the application, and review USCIS requests or appointment notices.
Every claim is fact-specific. Filing Form N-600 does not guarantee that USCIS will approve the application or issue a Certificate of Citizenship.

Discuss an N-600 ClaimNo. Form N-600 is an application for a certificate documenting citizenship. The applicant must already have acquired or derived citizenship under the applicable law and provide evidence of eligibility.
An eligible individual may generally file for themselves. In certain cases, a U.S. citizen parent or legal guardian may file for a minor child. Review current USCIS instructions to confirm who may file in a particular case.
Naturalization is a process through which an eligible permanent resident applies to become a U.S. citizen. Form N-600 is used by someone who claims they already became a citizen through a parent and seeks a Certificate of Citizenship as evidence of that status.
The required evidence depends on the claim. It may include birth and parentage records, proof of the parent’s U.S. citizenship, immigration records, and residence or custody evidence. Check current USCIS instructions and tailor the supporting documents to the case.
In some circumstances, a U.S. citizen parent or legal guardian may file on behalf of a minor child. The child must meet the applicable citizenship requirements, and the correct filing method depends on the specific claim.
An adult may generally apply for a Certificate of Citizenship if they can establish that they acquired or derived citizenship through a parent. The rules depend on the person’s birth date and family and immigration history.
Processing times vary based on USCIS workload, the completeness of the evidence, and case-specific issues. Check the USCIS processing-times tool for current estimates; posted times do not guarantee how long an individual case will take.
Differences in names, dates, or parent information should be reviewed before filing. Depending on the record and the claim, you may need corrected documents, additional evidence, or an explanation to help USCIS understand the discrepancy.
A U.S. passport is evidence of citizenship, but it is a different document issued through the Department of State. Whether a passport or Certificate of Citizenship best meets your documentation needs depends on your circumstances and the purpose for which you need proof.
