Naturalization requirements are the legal standards every immigrant must meet to become a U.S. citizen. This process transforms lawful permanent residents (green card holders) into full citizens with voting rights, U.S. passports, and greater immigration privileges.
If you plan to apply for naturalization, pay close attention to the updated eligibility, documentation, and interview requirements set by the U.S. Citizenship and Immigration Services (USCIS).
General Naturalization Requirements for All Applicants
To qualify for U.S. citizenship through naturalization, you must meet the following:
Basic Eligibility Criteria:
- Be at least 18 years old
- Be a lawful permanent resident (green card holder)
- Have continuous residence in the U.S. for the required period
- Demonstrate physical presence in the U.S.
- Show good moral character
- Speak, read, and write basic English
- Pass a U.S. civics test
- Support the U.S. Constitution and take the Oath of Allegiance
Each requirement must be met before submitting Form N-400, Application for Naturalization.

Continuous Residence and Physical Presence Explained
These two often confuse applicants. Here’s the difference:
| Requirement | What It Means | Duration |
|---|---|---|
| Continuous Residence | You have lived in the U.S. without long absences | 5 years (3 for spouses of U.S. citizens) |
| Physical Presence | You have been physically inside the U.S. for a minimum time | 30 months out of 5 years (or 18 out of 3 years) |
Trips abroad over 6 months can disrupt your continuous residence unless you prove otherwise.
English and Civics Requirements
USCIS tests your ability to:
- Read one English sentence
- Write one English sentence
- Speak basic English (evaluated during interview)
- Answer 6 out of 10 civics questions correctly (from a list of 100)
Exceptions apply for:
- Applicants over age 50 with 20 years of green card status
- Applicants over age 55 with 15 years of status
See: USCIS Civics Test Resources
Good Moral Character Requirement
This includes:
- No serious criminal convictions
- No immigration fraud
- Timely payment of taxes
- No false testimony
Officers review the last five years of your history (or three years if married to a U.S. citizen).
Special Naturalization Requirements for Spouses of U.S. Citizens
If you’re married to a U.S. citizen, you may apply for naturalization after 3 years (instead of 5), provided:
- You’ve lived in marital union for 3 years
- Your spouse has been a U.S. citizen the entire time
- You meet all other requirements (English, civics, moral character)
Apply using Form N-400.
Residence and Jurisdiction Rule
You must:
- Live for at least 3 months in the USCIS district or state where you apply
- Prove actual residency with leases, bills, or ID
Avoid switching addresses during the process unless absolutely necessary.
Military Naturalization Pathways
Members of the U.S. armed forces can apply under special rules. They may:

Documents Required for Naturalization
-
To successfully apply for naturalization, you must submit a complete and well-documented application. Missing or incorrect paperwork can lead to delays, requests for evidence (RFEs), or even denial. Below is a breakdown of essential documents required when filing Form N-400:
-
Permanent Resident Card (Green Card):
Submit clear copies of the front and back. This proves your legal permanent resident status and is a basic requirement for all applicants. -
State-Issued Photo Identification:
Provide a valid driver’s license or state ID that matches your current address. This confirms your identity and local jurisdiction eligibility. -
Marriage Certificate (if applying through a U.S. citizen spouse):
You must include your marriage certificate to show your marital relationship. If either spouse was previously married, also submit divorce or death certificates. -
Federal Tax Returns:
Include your last 3–5 years of tax transcripts from the IRS. These help establish good moral character and verify U.S. residence. Request at www.irs.gov. -
Selective Service Registration Proof (if male and between ages 18–26):
Men who lived in the U.S. during this age range must show registration with the Selective Service. Get a status letter at www.sss.gov. -
Travel History and Records:
Provide a list of all trips outside the U.S. during the past 5 (or 3) years, including dates and durations. This supports the continuous residence and physical presence requirement. -
Court and Police Records (if applicable):
If you’ve ever been arrested, cited, or convicted, include certified court dispositions and police reports. Full disclosure is essential, even for sealed or expunged cases. -
Name Change Documentation (if applicable):
If your legal name has changed due to marriage, court order, or any other reason, include supporting evidence such as a court decree or marriage certificate. -
Child Support and Custody Records (if applicable):
If you have dependents or child support obligations, USCIS may request proof of compliance and payment history.
Always submit legible copies of documents unless USCIS specifically asks for originals. Bring originals to your interview for verification. Organize your submission clearly and label documents to match Form N-400 questions.
