A green card is evidence of lawful permanent resident status. U.S. citizenship is a different status, and naturalization is one way an eligible person can become a citizen. Renewing a green card and applying for citizenship are separate processes—not two names for the same application. 1267
Understanding that distinction can help you organize the right questions before you start filling out forms.
What does a green card represent?
A Permanent Resident Card, commonly called a green card, documents lawful permanent resident status in the United States. Permanent residents generally may live and work in the country, subject to the responsibilities and limits of that status. 1
The expiration date printed on a card and the person’s immigration status are related, but they are not interchangeable. For example, replacing an expired card is a different question from whether someone has maintained permanent resident status. Conditional permanent residents also have a separate process for removing conditions; a routine card-renewal application is not a substitute for that process. 137
If you are unsure whether your card is conditional, or whether travel or another event has affected your status, get qualified legal advice before choosing a form.
What is naturalization?
Naturalization is the process through which an eligible person who is not already a U.S. citizen applies to become one. Form N-400 is the Application for Naturalization. Eligibility depends on the applicable category and individual circumstances, not simply on having a green card. 2
Residence, physical presence, travel history, and other requirements may matter. Marriage to a U.S. citizen does not automatically confer citizenship or establish eligibility on a particular date. Use the current USCIS instructions to understand the category that may apply to you. 2
Some people acquire citizenship at birth or through a parent under applicable law. Documentation of citizenship in those circumstances is different from an adult naturalization application. 48
Why do the different forms matter?
These form names describe different purposes:
- Form I-90: Application to Replace Permanent Resident Card.
- Form I-751: Petition to Remove Conditions on Residence for certain marriage-based conditional residents.
- Form N-400: Application for Naturalization.
- Form N-600: Application for Certificate of Citizenship. 2345
This is a guide to terminology, not a way to select a form based on a single fact. The current instructions explain who may use each form and what evidence is required.
What should you organize before asking for help?
Gather your existing card, relevant USCIS notices, copies of earlier applications, and a list of questions. If your question concerns citizenship, it can also help to organize address and travel histories so you can discuss gaps in the records.
Keep original documents safe. Do not send passport numbers, Social Security numbers, or copies of identity documents through a general website inquiry form.
