Do you believe you are already a United States citizen, even though you were born outside the U.S.? If you have a parent who is a U.S. citizen, you might have acquired citizenship automatically at birth or after you entered the United States. However, knowing you are a citizen and proving it are two different things.
This is where the N-600 application for certificate of citizenship comes in.
Unlike the naturalization process, which turns a permanent resident into a citizen, the N-600 is a request for a document that proves you already hold this status. It can be a confusing distinction, but getting it right is crucial. Filing the wrong form can cost you over a thousand dollars and months of waiting.
This guide will explain everything you need to know about Form N-600, who is eligible, and how to apply correctly.
ℹ️ Key Takeaways
- Purpose: Form N-600 provides proof of citizenship for those who acquired it automatically through parents.
- One Chance: You typically only get one shot at filing an N-600. If denied, you must appeal rather than re-apply.
- Cost: The filing fee is significantly higher than the standard naturalization application.
- Eligibility: Generally for biological or adopted children of U.S. citizens who are under 18, or adults who acquired citizenship before turning 18.
What Is Form N-600?
Form N-600, Application for Certificate of Citizenship, is a document filed with U.S. Citizenship and Immigration Services (USCIS). Its sole purpose is to issue a Certificate of Citizenship to someone who is already a U.S. citizen.
It is important to understand that this form does not make you a citizen. It asks the government to recognize that you are already a citizen under the law.
N-600 vs. N-400: What Is the Difference?
Many people confuse the N-600 with the N-400 application. However, they serve two very different groups of people:
- Form N-400 (Naturalization): This is for Green Card holders (Permanent Residents) who want to become U.S. citizens. They must pass English and civics tests and show good moral character.
- Form N-600 (Certificate of Citizenship): This is for people who derived or acquired citizenship through their parents. They generally do not need to take tests because they are claiming a status they already legally hold.
💡 Pro Tip
If you already have a U.S. passport, that is also valid proof of citizenship. However, a Certificate of Citizenship (obtained via N-600) is a permanent document that never expires, unlike a passport. It is excellent for long-term records.
Who Is Eligible for a Certificate of Citizenship?
Eligibility for the N-600 application for certificate of citizenship depends on immigration laws that were in effect when you were born or when your parents became citizens. Generally, there are two main ways to qualify:
1. Acquisition of Citizenship at Birth
This applies if you were born outside the United States to at least one U.S. citizen parent. The laws here can be complex and depend on:
- Which parent was a citizen (mother, father, or both).
- Whether your parents were married when you were born.
- How long your U.S. citizen parent lived in the U.S. prior to your birth.
2. Derivation of Citizenship After Birth
This applies to children born abroad who later become citizens automatically. Currently, under the Child Citizenship Act of 2000, a child typically becomes a citizen automatically if:
- At least one parent is a U.S. citizen (by birth or naturalization).
- The child is under 18 years old.
- The child is a Lawful Permanent Resident (Green Card holder).
- The child resides in the U.S. in the legal and physical custody of the U.S. citizen parent.
If you meet these conditions before turning 18, you are likely a citizen already. You can file Form N-600 to get the paper to prove it.
⚠️ Warning
If you are currently over 18, you can still file Form N-600, but only if you met all the requirements before you turned 18. If you did not meet the conditions until you were 19 or older, you usually cannot file N-600 and must file Form N-400 instead.
Required Documents for N-600
Because you only get one chance to file this form, your evidence must be perfect. USCIS needs to see the link between you and your U.S. citizen parent.
Common required documents include:
- Your Birth Certificate: Must show your parents’ names.
- Parents’ Birth Certificates or Naturalization Certificates: Proof that they are U.S. citizens.
- Parents’ Marriage Certificate: If applicable, to prove the relationship.
- Proof of Legal Custody: If parents are divorced or separated, you must prove the U.S. citizen parent had legal custody of you.
- Proof of Physical Residence: Evidence that the citizen parent lived in the U.S. for the required number of years (school records, tax returns, leases).
- Your Green Card: If you are claiming citizenship after birth.
- Two Passport-Style Photos.
🚀 Feeling Overwhelmed?
Gathering evidence for an N-600 application can be tricky. Missing one document can lead to a denial. Let Greenbroad handle the paperwork for you. We provide a complete application package and document checklist for a flat fee of $749.
Step-by-Step Filing Process
Step 1: Analyze Your Eligibility
Before you pay the fee, double-check the law. Did you truly acquire citizenship automatically? If you are unsure, you might waste a lot of money.
Step 2: Prepare Form N-600
You can file online or by mail. The form asks for detailed information about your biological parents and your history. You must be honest and accurate.
Step 3: Gather Supporting Documents
Collect certified translations for any document not in English. Organize your proof of residence and custody carefully.
Step 4: Submit and Pay Fees
The filing fee is expensive. As of 2024/2025, the fee is generally $1,385 for paper filing (online filing is slightly cheaper at $1,335). Check the official USCIS site for the exact current fee, as prices change.
Step 5: Biometrics Appointment
After filing, USCIS may send you a notice to have your fingerprints and photo taken. This is standard for background checks.
Step 6: The Interview (Sometimes)
Not every N-600 applicant needs an interview. If your documentation is clear, USCIS might skip it. However, if they have questions about your parents’ residence or your custody status, they will schedule an interview at a local field office.
Step 7: The Oath of Allegiance
If approved, and if you are over 14 years old, you must take the Oath of Allegiance. After the oath, you will receive your Certificate of Citizenship.
Processing Time and Costs
The N-600 application for certificate of citizenship is not cheap, nor is it fast.
- Cost: Expect to pay over $1,300 in government filing fees. This is nearly double the cost of the N-400 naturalization application.
- Timeline: Processing times vary significantly by field office. It typically takes between 6 to 14 months to receive a decision. Some complicated cases can take longer.
Because the cost is so high, many people wonder if it is worth it. While a U.S. passport is cheaper ($130-$165), passports expire. A Certificate of Citizenship is valid for life. It is the gold standard for proving your status to government agencies, schools, and employers.
Common Mistakes to Avoid
Filing Form N-600 is high-stakes. Avoid these common errors:
- Filing when you should file N-400: If you did not meet the automatic citizenship requirements before turning 18, filing N-600 will result in a denial and lost money. You likely need to file for naturalization instead.
- Insufficient Custody Evidence: This is the most common reason for denial in derivation cases. If your parents divorced, you must prove the U.S. citizen parent had legal and physical custody of you during the relevant years.
- Lack of Physical Presence Proof: If you are claiming citizenship at birth (born abroad), you must prove your parent lived in the U.S. for specific periods (often 5 years total, with 2 years after age 14). Affidavits are usually not enough; you need hard records like school transcripts or employment history.
ℹ️ Did You Know?
Children adopted by U.S. citizens from other countries typically use Form N-600K if they are residing outside the U.S., or the standard N-600 if they are living in the U.S. with a Green Card. The rules for adoption are specific, so check the requirements carefully.
Frequently Asked Questions
What is the N-600 application used for? Form N-600 is used to obtain a Certificate of Citizenship. It serves as proof that you are already a U.S. citizen, usually because you acquired citizenship automatically through your parents. It is not an application to become a new citizen.
What is the difference between Form N-400 and N-600? Form N-400 is an application for naturalization, used by Green Card holders to become U.S. citizens. Form N-600 is for individuals who are already citizens by law (usually through parents) but need an official document to prove it.
How much does it cost to file Form N-600? As of recent fee updates, the filing fee for Form N-600 is generally over $1,300. The fee is lower for active duty military members and adopted children in specific categories, so always check the latest USCIS fee schedule.

What happens if my N-600 application is denied? If your N-600 is denied, you generally cannot file a new one. Instead, you must file an appeal or a motion to reopen your case within 30 days. Because you typically get only one chance, it is vital to submit a complete and accurate application.
Conclusion
Securing your Certificate of Citizenship is a vital step in cementing your identity as an American. While a passport is great for travel, the certificate issued after an approved N-600 application for certificate of citizenship is a lifetime document that never needs renewal.
Because the government filing fee is high and you typically only get one chance to apply, accuracy is essential. Do not guess on your forms. Make sure you have the right evidence to prove your relationship to your parents and your residence history.
