Under the Child Citizenship Act (CCA), a foreign-born child generally derives United States citizenship automatically if at least one parent naturalizes before the child turns 18. The parent must have legal and physical child custody, and the child must hold a Green Card. To get official proof of this status in 2026, you file Form N-600 with USCIS, which currently carries a federal filing fee of $1,170.
Navigating the immigration system can feel overwhelming, especially when it involves the future of your children. Fortunately, United States law provides a beautiful pathway for families through the Child Citizenship Act (CCA). When a parent becomes a naturalized citizen, their foreign-born children may automatically gain citizenship too, without needing a separate naturalization test. This process is known as derived citizenship, and it offers immense peace of mind for families across the country, whether they reside in Texas, California, or Florida.
While the citizenship is granted automatically by law when all conditions are met, the government does not automatically mail you a certificate. 📄 To secure tangible proof, families usually file Form N-600, Application for Certificate of Citizenship. Having this official document protects your child from future immigration liability and makes it significantly easier to handle everyday tasks, like applying for a passport, updating records with the IRS, or eventually visiting the local DMV for a driver’s license. If you are unsure about your specific situation, it is always a smart idea to consult an attorney from our directory.
Step-by-Step Process in the United States
Whether you live in Houston (Harris County), Los Angeles, or Miami, the process for claiming derived citizenship is strictly a federal matter handled by U.S. Citizenship and Immigration Services (USCIS). Because the laws are federal, you will follow the same procedures across the entire United States. Generally, the process requires confirming the child’s eligibility and submitting a comprehensive application to the government.
Step 1: Meeting the Child Citizenship Act Requirements
Before filing any paperwork, you must ensure your child meets the specific criteria set by the Child Citizenship Act. 📋 Generally, the child must be under the age of 18 years old when the parent naturalizes. Additionally, the child must be living in the United States in the legal and physical child custody of the citizen parent, and the child must be admitted as a Lawful Permanent Resident (holding a Green Card). If the parents are separated, ensuring there are clear court orders regarding custody and no unresolved alimony/spousal support conflicts can help establish that the citizen parent truly has legal custody.
Step 2: Gathering Supporting Documents
USCIS requires solid proof that all the CCA conditions were met before the child’s 18th birthday. You will generally need the child’s birth certificate, the parent’s Certificate of Naturalization, the child’s Green Card, and evidence of living together. To prove residency, families often submit school records, medical bills, or tax transcripts from the IRS showing the child as a dependent.
Step 3: Submitting Form N-600
Once all documents are organized, you will fill out and submit Form N-600. 💻 This form can be filed online or sent by mail to the designated USCIS lockbox. Unlike personal injury lawsuits or civil claims that have a strict statute of limitations, there is no absolute deadline to file Form N-600. However, most experts strongly recommend filing it while the child is still young. Having this certificate prevents future headaches—for example, if the adult child ever becomes a plaintiff or defendant in a federal court case, or needs to file an EEOC complaint at work, having undeniable proof of United States citizenship is incredibly helpful.
Understanding the difference between deriving citizenship and applying for naturalization is crucial for families. Below is a general comparison of the two processes:
| Feature | Derived Citizenship (Form N-600) | Naturalization (Form N-400) |
|---|---|---|
| Age Requirement | Must be under 18 when parent naturalizes | Must be 18 or older to apply |
| Test Requirement | No English or Civics test required | Must pass English and Civics exams |
| Filing Fee (2026) | Generally $1,170 | Generally $710 – $760 |
How Much Does it Cost in the United States?
Applying for a Certificate of Citizenship requires paying specific federal government fees. Below is a breakdown of what you can generally expect to spend in 2026:
- USCIS Filing Fee: The standard filing fee for Form N-600 is currently $1,170. This fee is generally non-refundable, even if the application is denied.
- Attorney Fees: If your case is complicated by adoption, international custody disputes, or a previous settlement agreement with a former spouse, hiring a lawyer from our directory is wise. Immigration attorney fees for N-600 cases typically range from $800 to $2,500 across the United States.
- Translation Costs: If your child’s birth certificate is in a foreign language, you must provide a certified English translation. This usually costs between $20 and $50 per page.
- Passport Fees: Many parents also apply for a U.S. passport for their child, which currently costs around $135 for a minor.
How Long Does the Process Take?
Because USCIS receives thousands of applications, the timeline for processing Form N-600 can require some patience. ⏳ In 2026, most applicants wait between 5 and 10 months from the date USCIS accepts the application.
During this waiting period, USCIS may send a Request for Evidence (RFE) if they need more proof of child custody or physical presence. Once the application is approved, the applicant is typically scheduled to take the Oath of Allegiance (if the child is over 14 years old) and will receive their official Certificate of Citizenship.
Frequently Asked Questions (FAQ)
Do I have to file Form N-600 for my child?
No, it is not legally mandatory. A child who meets the CCA requirements is a United States citizen by law automatically. However, without a Certificate of Citizenship or a U.S. passport, the child may struggle to prove their status to the DMV, employers, or universities later in life.
What happens if my child turns 18 before I become a citizen?
If the child turns 18 before the parent takes the Oath of Allegiance, the child does not qualify for derived citizenship under the Child Citizenship Act. In this case, the adult child must apply for naturalization on their own using Form N-400.
Can a child derive citizenship from a step-parent?
Generally, no. The law specifically states that step-children do not automatically derive citizenship from a step-parent. The relationship must be biological or through a finalized legal adoption before the child turns 16.
Can I get a fee waiver for the $1,170 filing cost?
Yes. If you have a documented financial hardship, receive a means-tested government benefit, or your income falls below certain federal poverty guidelines, you may file Form I-912 to request a fee waiver for the N-600 application.
Does my child have to attend an interview?
In many N-600 cases, USCIS waives the interview requirement if the submitted evidence clearly proves eligibility. However, if there are discrepancies regarding child custody or residency, the federal officer may request an in-person interview.
