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.
