Naturalization and the N-400: Your Path to U.S. Citizenship in 2026

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:

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 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:

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:

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:

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.

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

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

Can I file my N-400 90 days before my fifth anniversary as a permanent resident?
Yes. USCIS permits you to file up to 90 calendar days before completing the five-year continuous residence requirement (or three-year requirement under INA 319). This is known as the 90-day early filing rule and is written into Section 334(a) of the Immigration and Nationality Act. You must still complete the full five or three years by the time the oath is administered. Filing even one day earlier than permitted will result in a denial and loss of the filing fee.
What if I traveled abroad for more than six months during the statutory period?
A single trip of six months or more creates a presumption that you broke continuous residence. That presumption is rebuttable with evidence that you maintained your U.S. home, employment, tax residency, and family ties. A trip of one year or more generally breaks continuous residence outright, and you typically have to restart the clock from the day after you returned, minus one year and a day, before you can file again. These rules are unforgiving, so do not file without reviewing your travel history carefully.
I have a criminal record. Should I still apply?
Not without legal advice. Some convictions create permanent bars to naturalization and can even render you removable. Applying for naturalization exposes you to renewed scrutiny of your criminal history, and USCIS can refer you to immigration court if removal grounds surface. Before you file, gather certified court dispositions for every arrest (whether or not a conviction followed) and meet with an immigration attorney to assess the risk.
Do I have to take the new 2025 civics test?
It depends on when you filed. If your N-400 was filed on or after October 20, 2025, you take the 2025 test of up to 20 questions drawn from 128, and you must answer 12 correctly. If you filed before October 20, 2025, you continue to take the 2008 version. USCIS provides study materials on its Citizenship Resource Center for both versions.
Can I keep my Brazilian or other original citizenship after naturalizing?
U.S. law does not force you to give up your original citizenship. Whether you can keep it depends on your home country. Brazil expressly permits dual citizenship, and Brazilian citizens who naturalize in the United States do not lose their Brazilian citizenship. Other countries follow different rules, so confirm with your home country's consulate before taking the Oath of Allegiance.
What if I fail the English or civics test at my interview?
If you fail one or both portions at the first interview, USCIS gives you a second chance. You are rescheduled for a second interview typically 60 to 90 days later, and you are tested only on the portion you failed. If you fail again at the second interview, USCIS denies the N-400 and you have to refile and pay the fee again. Study materials are free on the USCIS website, and community organizations often offer citizenship classes.

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.
