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.

I was skeptical about editing pdfs on my phone, but Zendocs made it work smoothly. Filled out a freelance w9 while waiting for my coffee. No issues at all.

I'm a screenwriter and mark up my drafts often. Tried the annotate pdf tool here – it was actually pleasant to use. Notes stuck where I placed them, colors were clear, and export kept everything intact. Beats printing 80 pages every time.

Used ZenDocs to split up a 100-page policy doc into smaller team manuals. It was quick, intuitive, and didn't crash once – even with that massive file.

Compiled my speaker bio, session outline, and visual aids into one file for a conference. ZenDocs let me combine them fast and add bookmarks for each section. This made navigating during my talk so much easier. I even re-uploaded the final version to make a few changes – every step was smooth. Really appreciated how consistent the UI was.

I needed to add quick comments to student feedback forms and the annotate pdf feature on zen docs made it painless. No crashes, super clean interface – definitely easier than Adobe's bloated editor.

ZenDocs has the cleanest interface I've used. Edited a PDF proposal, reordered some sections, and exported without hassle. It just works.
