Everything You Need to Know About the N-600 Form

What is Form N-600?

The N-600 is the application to obtain a Certificate of Citizenship. It confirms your U.S. citizenship status if you automatically became a citizen through your parents either at birth or after birth.

Why do I need a Certificate of Citizenship?

• To provide official proof of your U.S. citizenship.
• To apply for a U.S. passport or federal benefits.
• To demonstrate your eligibility for work and voting.

Who should file Form N-600?

• Individuals born abroad to U.S. citizen parents.
• Children who derived citizenship after birth through naturalized parents.
• Adopted children meeting citizenship requirements under the INA.

What documents are required?

• Proof of parent’s U.S. citizenship.
• Applicant’s birth certificate or adoption decree.
• Parent’s marriage/divorce certificates (if applicable).
• Legal custody or physical presence records.

When should I apply for N-600?

You can apply at any age, but USCIS recommends doing so early to avoid complications when applying for passports, benefits, or employment.

What’s the difference between N-600 and N-400?

• N-600: Used to document citizenship already acquired through parents.
• N-400: Used to apply for naturalization after meeting residency requirements.

How is N-600 different from a passport application?

While both provide proof of citizenship, the N-600 certificate is permanent, issued once, and can’t expire, whereas passports must be renewed regularly.

Processing tips:

• Filing online is generally faster than paper.
• You should prepare all required documents in advance, including certified copies where needed.
• Adopted children may require additional documentation, such as a full and final adoption decree.
