What Naturalization Means
Naturalization is the legal process by which a lawful permanent resident (green card holder) becomes a United States citizen. For many people, it marks the final step of a long immigration journey. It also unlocks rights that no visa or green card can provide: the right to vote in federal elections, the right to hold a U.S. passport, complete protection from deportation on immigration grounds, the ability to petition for more categories of family members, and access to jobs reserved for citizens.
The central form in the naturalization process is Form N-400, Application for Naturalization. This guide walks you through who qualifies, what the application costs in 2026, how the new 2025 civics test works, what happens at the interview, and how to handle common problems that come up along the way.
Every case is different. The rules below describe the general pathway for most applicants. If you have a criminal record, extended trips outside the United States, unpaid taxes, or concerns about how you obtained your green card, please talk to an experienced immigration attorney before you file.
Who Qualifies to Apply on Form N-400
Most applicants fall into one of two main pathways under the Immigration and Nationality Act.
The Five-Year Rule Under INA 316
Under Section 316 of the Immigration and Nationality Act, a lawful permanent resident may apply for naturalization after five years of continuous residence in the United States. To qualify on this pathway, you must be:
- At least 18 years old at the time of filing
- A lawful permanent resident for at least five years immediately before filing
- Continuously resident in the United States for those five years
- Physically present in the United States for at least 30 months out of the five-year period
- A resident of the state or USCIS district where you file for at least three months before filing
- A person of good moral character during the statutory period and up to the oath
- Attached to the principles of the U.S. Constitution
- Able to read, write, and speak basic English (with limited exceptions based on age and length of residence)
- Able to pass the civics test (again, with limited exceptions)
The Three-Year Rule for Spouses of U.S. Citizens
Under Section 319(a) of the Immigration and Nationality Act, a lawful permanent resident married to a U.S. citizen may apply after three years, rather than five, if all of the following are true during the three-year period before filing:
- You have been a lawful permanent resident for at least three years
- You have been married to and living with the same U.S. citizen spouse for those three years
- Your spouse has been a U.S. citizen for the full three years
- You have been physically present in the United States for at least 18 months of those three years
You still have to meet the three-month state or district residence requirement, the good moral character standard, the English and civics requirements, and the attachment to the Constitution requirement. If you stop living with your U.S. citizen spouse (through separation, divorce, or death) before the oath, you generally lose eligibility under this faster pathway.
Other Pathways
A number of additional categories exist for people with specific circumstances:
- Military service: Service members and veterans with qualifying service under INA 328 or INA 329 may qualify under special rules, and filing fees may be waived
- VAWA self-petitioners: A person who became a lawful permanent resident through a VAWA self-petition may qualify after three years under Section 319(a)
- Children of U.S. citizens: Children under 18 who live in the legal and physical custody of a U.S. citizen parent typically acquire citizenship automatically under the Child Citizenship Act and do not file Form N-400
Continuous Residence and Physical Presence Explained
These two concepts sound similar but measure different things, and they trip up a lot of applicants.
Continuous Residence
Continuous residence means that your primary home has been in the United States without a break for the required five-year or three-year period. A trip abroad of six months or more but less than one year creates a rebuttable presumption that you broke continuous residence. A trip of one year or more will generally break continuous residence entirely unless you obtained a reentry permit and certain other conditions apply.
If you have been away for a long trip, you are not automatically disqualified. You can present evidence to rebut the presumption, such as retained U.S. employment, a maintained U.S. home, continued tax filings as a resident, and family remaining in the United States. Plan your filing date carefully and, when in doubt, consult an attorney before submitting your application.
Physical Presence
Physical presence is a straightforward accounting of days on U.S. soil. You must have been physically present in the United States for at least 30 months out of the five-year period, or at least 18 months out of the three-year period if you qualify through marriage to a U.S. citizen. USCIS will ask you to list every trip abroad during the statutory period, including the date you left and the date you returned, so keep your records and passport stamps ready.
Practical Tip: Before you file, add up every trip you took outside the United States during the statutory period. If the total exceeds half of your statutory period, you do not meet the physical presence requirement and need to wait longer before filing. A small margin is dangerous. Travel records, boarding passes, and I-94 history from the CBP website can help you reconstruct dates if your memory is fuzzy.
Good Moral Character
Good moral character (often shortened to GMC) is one of the most important and misunderstood requirements. Under INA 316(a)(3) and 8 C.F.R. 316.10, you must show that you were a person of good moral character during the statutory period and continue to be one up to the oath of allegiance. USCIS may also look at conduct before the statutory period if it is relevant.
Certain conduct creates statutory or conditional bars to a finding of good moral character, including:
- Conviction of an aggravated felony after November 29, 1990 (a permanent bar)
- Conviction of a crime involving moral turpitude during the statutory period
- Conviction of two or more offenses with an aggregate sentence of five years or more
- A controlled substance conviction (with a narrow exception for a single offense of simple possession of 30 grams or less of marijuana)
- Confinement in a penal institution for 180 days or more during the statutory period
- Giving false testimony under oath to obtain an immigration benefit
- Failure to support dependents, failure to file or pay required taxes, and certain other conduct that USCIS considers on a case-by-case basis
USCIS policy on how officers evaluate good moral character has shifted over the years, and in 2025 USCIS issued a policy memorandum instructing officers to apply a more holistic and stricter evaluation rather than treating the list of bars as exhaustive. Even conduct that does not trigger a specific statutory bar can weigh against you if the officer concludes your overall conduct falls below the standards of the average citizen in your community.
If you have any arrest or conviction in your history, even one that was dismissed or expunged, bring the certified court disposition to your attorney before you file.
English and Civics Requirements
At the naturalization interview, a USCIS officer tests your ability to read, write, and speak basic English, and your knowledge of U.S. history and civics. The rules for the civics test changed in 2025.
The 2025 Civics Test
For Form N-400 applications filed on or after October 20, 2025, USCIS administers the 2025 civics test. The officer asks up to 20 questions drawn from a list of 128 civics questions. You must answer 12 correctly to pass. This is a significant change from the 2008 version, which used a list of 100 questions and required 6 correct answers out of up to 10 questions asked.
Applicants who filed before October 20, 2025 and are still waiting for their interview continue to take the 2008 version of the test. The version that applies to you is the one in effect on the date you filed, not the date of the interview.
Age-Based Exceptions
Two long-standing exceptions reduce the burden of the test for older applicants who have been lawful permanent residents for many years:
- 50/20 exception: If you are age 50 or older at the time of filing and have lived in the United States as a lawful permanent resident for at least 20 years, you are exempt from the English language requirement and may take the civics test in your native language with the help of an interpreter you provide
- 55/15 exception: If you are age 55 or older at the time of filing and have lived in the United States as a lawful permanent resident for at least 15 years, the same English waiver applies
- 65/20 special consideration: If you are 65 or older at the time of filing and have been a lawful permanent resident for at least 20 years, you also receive a simplified civics test drawn from a smaller subset of questions
Medical Disability Exception (Form N-648)
If a physical or developmental disability or mental impairment prevents you from meeting the English or civics requirements, a licensed medical professional can complete Form N-648 to request a waiver. The doctor must explain the diagnosis, describe how it affects your ability to learn, and connect that impairment to the specific requirement being waived.
Filing Fees in 2026
Filing fees increased under the USCIS fee rule that took effect on April 1, 2024, and those amounts remain in place in 2026.
- Standard filing fee: $710 if you file online, $760 if you file by paper
- Reduced fee: $380 for applicants with household income between 150 percent and 400 percent of the federal poverty guidelines, requested on Form I-942
- Fee waiver: Available on Form I-912 for applicants who receive a means-tested public benefit, have household income at or below 150 percent of the federal poverty guidelines, or can show financial hardship
- Military applicants: Active-duty service members and veterans with qualifying service under INA 328 or 329 may file at no cost
Biometric services (fingerprints) are included in the filing fee and are not billed separately.
Payment Method Update: As of October 28, 2025, USCIS no longer accepts paper checks or money orders for most filings, including Form N-400. Applicants who file by paper must pay by credit card using Form G-1450 or by ACH bank transfer using Form G-1650. Online filers pay directly through the USCIS online filing portal.
The Naturalization Process Step by Step
Step 1: Confirm Eligibility
Before you file, review the eligibility checklist at the beginning of this guide. Pay special attention to continuous residence, physical presence, good moral character, and any trips abroad. If anything is borderline, talk to an attorney.
Step 2: Gather Documents
Typical documents include your green card, all passports covering the statutory period, marriage and divorce certificates where relevant, tax transcripts or returns, court dispositions for any arrests, and evidence of selective service registration for male applicants between the ages of 18 and 26.
Step 3: File Form N-400
You can file online through your myUSCIS account or by paper to the appropriate Lockbox facility. Online filing offers a lower fee, faster confirmation of receipt, and the ability to upload evidence and check status through the portal.
Step 4: Biometrics Appointment
A few weeks after filing, USCIS schedules a biometrics appointment at an Application Support Center. USCIS collects fingerprints, a photo, and a signature for the background check. In many cases USCIS reuses biometrics already on file and may waive the appointment.
Step 5: Interview and Tests
At your interview, an officer reviews your N-400 under oath, tests your ability to read, write, and speak basic English, and administers the civics test. Bring every document USCIS requested in the appointment notice, plus copies of anything else that has changed since you filed.
Step 6: Decision
USCIS may grant your application on the spot, continue the case for additional evidence or a second interview, or deny it. A denial can often be overcome by filing a request for a hearing on Form N-336 within 30 days, or by filing a new N-400 after addressing the issue.
Step 7: Oath of Allegiance
Approved applicants take the Oath of Allegiance at a ceremony administered by USCIS or a federal court. You become a U.S. citizen at the moment you take the oath and receive your Certificate of Naturalization. From that day you can apply for a U.S. passport, register to vote, and update federal records such as your Social Security file.
Processing Times in 2026
USCIS reports that N-400 processing times in 2026 average about 7.8 months nationally, although the range varies from roughly 5.5 months at the fastest field offices to 13 months or more at the slowest. A surge of filings in late 2025 pushed the backlog above 630,000 pending cases by January 2026, which is why many applicants are waiting longer than the historical median of 5 to 6 months.
You can check current processing times for your specific field office on the USCIS processing times page. If your case is outside the posted normal range, you may submit an inquiry through your myUSCIS account.
Common Reasons N-400 Applications Are Denied or Delayed
- Trips outside the United States that break continuous residence or physical presence
- Criminal history that triggers a statutory bar or undermines good moral character
- Unpaid taxes or failure to file required returns
- Failure to register for the Selective Service when required
- Child support arrears or unpaid court-ordered family obligations
- Inconsistent statements across the green card application, travel history, and N-400
- Misrepresentation or fraud in the original green card process
- Failure to disclose an arrest, even one that was dismissed
Most of these problems can be fixed or explained before filing. A pre-filing consultation with an immigration attorney is much less expensive than a denial.
Dual Citizenship
U.S. law does not require you to give up your original citizenship when you naturalize. The Oath of Allegiance does require you to renounce any foreign prince, potentate, state, or sovereignty to whom you previously owed allegiance, but that language has been interpreted narrowly for more than a century. Whether your home country allows you to keep your original citizenship is a separate question controlled by that country's law. Brazil, Mexico, the Dominican Republic, the United Kingdom, Ireland, and many other countries permit dual citizenship. Some countries do not, so check with your home country's consulate before taking the oath.
Frequently Asked Questions About Naturalization
Why Naturalization Matters
Citizenship changes your relationship with the United States. A permanent resident can still lose status through a serious criminal conviction or an extended absence. A U.S. citizen generally cannot be removed on immigration grounds. A citizen can vote in federal, state, and local elections, serve on a jury, travel with a U.S. passport, and sponsor a wider circle of family members for green cards, including parents, married adult children, and siblings.
For many immigrants, naturalization is also a psychological milestone. It ends years of uncertainty and affirms that the life you have built here is fully yours. It protects your ability to stay during political or policy changes that affect lawful permanent residents. And it gives the next generation in your family full U.S. citizenship at birth if they are born abroad after you naturalize.
How an Attorney Can Help
Many straightforward N-400 cases can be filed without an attorney. A lawyer becomes valuable when your situation includes any of the following: a criminal record, long or frequent trips abroad, unpaid taxes, a prior removal order, concerns about how you obtained your green card, divorce during the three-year marriage pathway, or confusion about selective service registration. An attorney can review your file before you submit, draft explanations for issues in your record, represent you at the interview, and file appeals if the case is denied.
