Naturalization is the legal process through which an eligible lawful permanent resident becomes a United States citizen. In 2026, most applicants must satisfy residence, physical presence, good moral character, English-language, and civics requirements before USCIS approves Form N-400, Application for Naturalization.
This guide explains the principal steps, current filing requirements, 2025 civics test that applies in 2026, and issues that may require advice from an immigration lawyer.
Important: Immigration law is fact-specific. This article provides general information as of August 12, 2026. It is not legal advice and does not replace an individualized case evaluation.
Step 1: Confirm That You Meet the Naturalization Requirements
Most applicants must satisfy all of the following requirements:
- Be at least 18 years old when filing Form N-400.
- Be a lawful permanent resident.
- Have maintained continuous residence in the United States for the applicable period.
- Have been physically present in the United States for the required number of days.
- Have lived in the same state or USCIS district for at least three months before filing.
- Demonstrate good moral character.
- Demonstrate an understanding of basic English, unless an exception applies.
- Demonstrate knowledge of U.S. history and government.
- Show attachment to the principles of the U.S. Constitution.
- Be willing to take the Oath of Allegiance.
The five-year rule
Most lawful permanent residents may apply after five years of continuous residence. The applicant generally must also show at least 30 months, or 913 days, of physical presence in the United States during the five-year statutory period.
The three-year rule for certain spouses
A lawful permanent resident married to a U.S. citizen may qualify under the three-year provision. The applicant generally must:
- Have been a lawful permanent resident for at least three years.
- Have lived in marital union with the same U.S. citizen spouse during that period.
- Have a spouse who has been a U.S. citizen for at least three years.
- Have been physically present in the United States for at least 18 months, or 548 days, during the three-year period.
Other specialized provisions may apply to certain VAWA applicants, military service members, and spouses of U.S. citizens employed abroad.
Early filing
USCIS generally permits eligible applicants to file Form N-400 up to 90 calendar days before completing the required three- or five-year continuous residence period. Early filing does not waive the other requirements. You must satisfy all applicable eligibility criteria when you file.
A filing made before the permitted 90-day period may be rejected or denied. Use the “Resident Since” date on your green card when calculating eligibility.
Step 2: Review Travel, Residence, and Employment History
Form N-400 requires detailed information about your residence, employment, education, and international travel. Prepare this information before beginning the application.
You should compile:
- Every physical address for the required three- or five-year period.
- Each employer and school attended during that period.
- Every trip outside the United States, including departure and return dates.
- Your current and former marital information.
- Information about your children.
- Details regarding arrests, citations, charges, convictions, probation, or alternative sentencing.
- Tax filing and payment information.
- Selective Service registration information, if applicable.
Continuous residence and physical presence are different
Continuous residence concerns whether you maintained your principal residence in the United States. Physical presence concerns the number of days you were actually in the country.
An absence of more than six months but less than one year may create a presumption that continuous residence was interrupted. An absence of one year or more generally breaks continuous residence unless a specific statutory exception applies.
Travel records must be accurate. Inconsistencies between Form N-400, passport records, and government databases can result in delays, additional questioning, or a denial.
Step 3: Gather Supporting Evidence
USCIS identifies evidence that may be required based on your filing basis and personal history. Generally, submit clear copies unless the form instructions require an original document.
Common documents include:
- Copies of both sides of your Permanent Resident Card.
- Marriage certificates and evidence of termination of prior marriages, if applicable.
- Proof of your spouse’s U.S. citizenship if applying under the three-year provision.
- Evidence addressing extended trips outside the United States.
- Certified court dispositions and sentencing records.
- Evidence that probation, parole, fines, restitution, or alternative sentencing obligations were completed.
- Tax payment agreements and proof of compliance if you owe taxes.
- Child or spousal support payment records, if applicable.
- Selective Service documentation, if required.
- Form N-648, Medical Certification for Disability Exceptions, if requesting a qualifying testing exception.
Foreign-language documents require a complete English translation. The translator must certify that the translation is accurate and that the translator is competent to translate from the foreign language into English.
Do not submit original documents unless USCIS specifically requires them. Bring originals or certified copies to the interview when appropriate.
Step 4: Complete and File Form N-400
USCIS currently lists two filing methods for Form N-400.
Online filing
You may file online through a USCIS online account if you are paying the standard filing fee. Online filing allows you to:
- Pay the filing fee electronically.
- Upload supporting evidence.
- Receive electronic notifications.
- Track case updates.
- Respond to certain USCIS requests.
- Update contact information.
The current standard online filing fee is $710.
Paper filing
You must file a paper Form N-400 if you are requesting a reduced fee or fee waiver. The current standard paper filing fee is $760.
The current reduced fee is $380 for eligible applicants whose documented annual household income is not more than 400 percent of the Federal Poverty Guidelines. Form N-400 instructions identify the evidence required to support the request.
Eligible applicants may also request a fee waiver using Form I-912. A fee waiver request must be filed on paper with the Form N-400 and supporting financial documentation.
USCIS may reject an application submitted with an incorrect fee, incorrect payment method, missing signature, incomplete pages, or an outdated form edition. Confirm the current fee and form edition immediately before filing through the official USCIS Form N-400 page.
Step 5: Attend Biometrics and Background Checks
USCIS may require biometrics, including fingerprints, a photograph, and a signature. These procedures support identity verification and criminal and national security background checks.
If USCIS schedules a biometrics appointment, attend as directed. Failure to appear may result in denial of the application.
After filing, monitor your USCIS account and mail carefully. USCIS may issue appointment notices, requests for evidence, or other case correspondence.
Step 6: Prepare for the Naturalization Interview
The naturalization interview is a formal examination of your eligibility and the information in your Form N-400. The officer may ask about:
- Your application responses.
- Your residence and travel history.
- Your employment and family history.
- Your immigration history.
- Arrests, citations, or criminal matters.
- Tax filing and payment.
- Child or spousal support obligations.
- Your willingness to take the Oath of Allegiance.
You must answer truthfully and consistently. A material misrepresentation or omission may result in denial and may create additional immigration consequences.
Step 7: Take the English and 2025 Civics Tests
Applicants who filed Form N-400 on or after October 20, 2025, generally take the 2025 naturalization civics test. This is the test administered to applicants in 2026.
English test
The English examination includes:
- Speaking: The USCIS officer evaluates your ability to understand and respond in English during the interview.
- Reading: You must read one of three sentences correctly.
- Writing: You must write one of three sentences correctly.
2025 civics test
The 2025 civics test is an oral examination based on a list of 128 questions. The officer asks up to 20 questions. You must answer at least 12 correctly to pass.
USCIS provides official 2025 civics test questions and study materials. Use those materials rather than relying on unofficial study guides.
If you fail the English or civics test, USCIS generally provides a second opportunity to pass the portion you failed. The retest usually occurs between 60 and 90 days after the initial interview.
Exceptions and accommodations
Some applicants may qualify for an exception or modification:
- 50/20 exception: At least 50 years old and a lawful permanent resident for at least 20 years.
- 55/15 exception: At least 55 years old and a lawful permanent resident for at least 15 years.
- 65/20 special consideration: Applicants at least 65 years old with at least 20 years as lawful permanent residents may take a simplified civics test.
- Medical exception: A qualifying physical or developmental disability or mental impairment may support an exception through Form N-648.
Review the official USCIS exceptions and accommodations information before filing.
Step 8: Receive a Decision and Take the Oath
USCIS may approve, continue, or deny the application. If USCIS approves your Form N-400, you must attend a naturalization ceremony and take the Oath of Allegiance.
You do not become a U.S. citizen merely because USCIS approves the application. Citizenship generally occurs after you take the Oath. USCIS then issues a Certificate of Naturalization.
The oath ceremony is therefore a required legal step, not an optional administrative formality.
Common Naturalization Problems in 2026
Applicants should obtain legal advice before filing if they have:
- Extended or frequent international travel.
- A criminal record, arrest, citation, diversion, or expunged matter.
- Unpaid or unfiled taxes.
- Unresolved child or spousal support obligations.
- Prior removal proceedings or immigration violations.
- Inconsistent information in prior immigration filings.
- A conditional green card with a pending Form I-751 or Form I-829.
- Possible Selective Service registration problems.
- Difficulty meeting the English or civics requirements.
- A history involving a family-based petition, humanitarian benefit, or work visa.
A work visa alone does not create eligibility for naturalization. In most cases, the applicant must first obtain lawful permanent resident status and then satisfy the applicable naturalization requirements. A family-based green card, employment-based green card, or another qualifying path may lead to naturalization if all statutory requirements are met.
