Key Takeaways

• N-400 processing time: 6 to 10 months as of April 2026 (fastest since 2016).
• Standard path: 5 years as a Lawful Permanent Resident + 30 months of physical presence.
• Married to a U.S. citizen: 3-year LPR path with reduced physical presence requirements.
• New 128-question civics test applies to all N-400 filings from October 20, 2025.
• Filing fee: $760 (verify current amount at USCIS.gov; fee waivers available).
• Must be at least 18 years old, able to read/write/speak basic English (with age-based exceptions).
• U.S. does not require giving up prior citizenship — dual nationality is common.

Becoming a U.S. citizen is one of the most meaningful milestones in an immigrant’s life. It confers the right to vote, the ability to petition for a wider range of family members, protection from deportation, and access to federal employment and benefits unavailable to permanent residents. In 2026, the process is more streamlined than it has been in years, with processing times at a decade-long low and updated study materials for the revised civics test. But the requirements remain strict, and preparation matters.

Understanding How to become a U.S. citizen is essential for many immigrants seeking a better life. How to become a U.S. citizen involves various steps and requirements that must be fulfilled.

This guide covers every eligibility requirement, the step-by-step application process, the 2026 civics test changes, English language requirements, fees, and common mistakes that delay or sink naturalization applications.

One of the most important topics to consider when learning How to become a U.S. citizen is the naturalization process. How to become a U.S. citizen is often a question that many ask, and this guide aims to answer it thoroughly.

Who Is Eligible for U.S. Naturalization?

When you ask how to become a U.S. citizen, it’s vital to understand the eligibility criteria, including the paths available for naturalization.

SSteps on How to Become a U.S. Citizen

Most people naturalize through the standard 5-year LPR path or the 3-year path for spouses of U.S. citizens. Both paths have specific requirements that go beyond simply having a green card. According to USCIS, all naturalization applicants must be at least 18 years old at the time of filing.

Knowing how to become a U.S. citizen is empowering, and understanding each requirement ensures you are well-prepared for the journey.

Standard 5-Year Path (Most Common)

• Lawful Permanent Resident for at least 5 years before filing
• Continuous residence in the U.S. for 5 years immediately before filing
• Physically present in the U.S. for at least 30 months out of the 5 years before filing
• Resided for at least 3 months in the state or USCIS district where you file
• Good moral character during the entire statutory period (5 years)
• Ability to read, write, and speak basic English
• Knowledge of U.S. history and government (civics test)
• Attachment to the principles of the U.S. Constitution and willingness to take the Oath of Allegiance

3-Year Path: Married to a U.S. Citizen

If you obtained your green card through marriage to a U.S. citizen and have been living in marital union with that same citizen throughout the 3-year statutory period, you may qualify under the shorter timeline:

For those wondering how to become a U.S. citizen through marriage, the process is designed to recognize the bond you share with your spouse.

• LPR for at least 3 years
• Married to and living with the same U.S. citizen for all 3 years
• Continuous residence for 3 years
• Physical presence for at least 18 months out of the 3 years
• All other standard requirements (moral character, English, civics)

Special Paths

• Military service: U.S. armed forces members who served honorably during periods of hostility may apply immediately, with no prior LPR period required in some cases.
• Children of U.S. citizens: Children born outside the U.S. to at least one U.S. citizen parent may automatically acquire citizenship and only need to apply for a U.S. passport or Certificate of Citizenship, not naturalize.
• Surviving spouses of U.S. citizens who died in combat: Special expedited processing applies.

Continuous Residence vs. Physical Presence: Understanding the Difference

These two requirements confuse many applicants, and violating either can reset the clock or disqualify you entirely.

It’s crucial to understand the difference between continuous residence and physical presence to know how to become a U.S. citizen effectively.

Continuous Residence

Continuous residence means you have maintained the U.S. as your primary home throughout the statutory period. A single trip abroad of more than 6 months but less than 1 year creates a presumption of broken continuous residence, which you can rebut with evidence (employment, family ties, paying U.S. taxes, keeping a U.S. home). A single trip of 1 year or more automatically breaks continuous residence, and you must restart the 5-year clock upon return.

Physical Presence

Physical presence is simply counting the days you were physically inside the United States. You need at least 30 months (for the 5-year path) or 18 months (for the 3-year path) out of the statutory period. This is a raw day count, not about where your primary residence is. Keep a travel log — passport stamps and I-94 records are what USCIS uses to verify this.

Early Filing Rule

You may file the N-400 up to 90 days before you meet the 5-year (or 3-year) continuous residence requirement. This means you can file at 4 years and 9 months of LPR status if you meet all other requirements. The naturalization will not be approved until you have actually met the full time requirement.

For applicants curious about how to become a U.S. citizen, it’s essential to remember that the N-400 form is the starting point of this process.

The 2026 Civics Test: What Changed and How to Prepare

Applicants who filed Form N-400 on or after October 20, 2025 take the revised 128-question civics test. Those who filed before that date take the prior 100-question test — if your case is still pending from a pre-October 2025 filing, confirm which version applies to your interview date with your attorney.

How the New 128-Question Test Works

• USCIS publishes all 128 official questions and acceptable answers on their website
• At your naturalization interview, the officer asks you 20 questions from the list
• You must answer at least 12 of the 20 questions correctly to pass (60% threshold)
• If you fail the first time, you get one more opportunity at a rescheduled interview, typically 60 to 90 days later
• The test is oral — you answer verbally, not in writing

Civics Test Exemptions

• 50/20 exemption: Applicants age 50 or older who have been LPRs for at least 20 years may take the civics test in their native language.
• 55/15 exemption: Applicants age 55 or older who have been LPRs for at least 15 years may also take the civics test in their native language.
• Medical disability waiver: Applicants with a medically documented physical or developmental disability or mental impairment that prevents learning English and/or civics may apply for a waiver using Form N-648.

English Language Requirement

Applicants between ages 18 and 50 with fewer than 20 years of LPR status must demonstrate basic English proficiency in three areas during the naturalization interview:

Part of how to become a U.S. citizen involves demonstrating English proficiency, which can be a critical part of your interview.

• Speaking: The interview itself tests your spoken English ability.
• Reading: The officer asks you to read one of three English sentences correctly.
• Writing: The officer dictates one of three simple sentences for you to write in English.

The English tested is basic conversational level, not academic. Most applicants who have lived and worked in the U.S. for several years pass this without special preparation. If English is a significant barrier, formal ESL classes or working with an immigration attorney who offers language-accessible services can help.

Good Moral Character: What USCIS Reviews

Good moral character is evaluated over the entire statutory period (5 or 3 years) before filing. USCIS looks at criminal history, tax compliance, selective service registration (for eligible males), immigration violations, and financial obligations.

Automatic Bars to Good Moral Character

• Murder conviction at any time (permanent bar)
• Conviction for an aggravated felony after November 29, 1990 (permanent bar)
• Persecutor of persons based on race, religion, national origin, or political opinion
• Unlawful voting or false citizenship claims

Conditional Bars (Within the Statutory Period)

• Habitual drunkard
• Illegal gambling, prostitution, or drug trafficking offenses
• Confinement in a penal institution for 180 days or more
• Two or more gambling offenses
• Failure to pay court-ordered child support or alimony
• False testimony to obtain immigration benefits

Many applicants with old minor offenses still qualify for naturalization, but full disclosure is essential. Attempting to hide a criminal record from USCIS is a federal crime and results in permanent ineligibility.

When considering how to become a U.S. citizen, being aware of your moral character is vital as it significantly influences your application.

How to Apply for Naturalization: Step-by-Step

Step 1: Confirm Eligibility

Check your green card for condition status, calculate your continuous residence and physical presence dates, and review your criminal history. If you have any arrests, even without conviction, consult an immigration attorney before filing.

Step 2: File Form N-400

File Form N-400 (Application for Naturalization) with USCIS online or by mail. The filing fee is $760 (verify current amount at USCIS.gov, as fees are periodically adjusted). Include:

• Copies of your green card (both sides)
• Passport photos (if filing by mail)
• Travel history for the past 5 years
• Marital history and any divorce records
• Selective Service registration proof (if applicable)
• Tax return transcripts for the statutory period
• Any criminal records (even arrests without conviction)
• Form N-648 (if applying for medical disability waiver)

Step 3: Biometrics Appointment

USCIS schedules a biometrics appointment at a local Application Support Center (ASC) to collect your fingerprints and photograph. This typically occurs 4 to 8 weeks after filing. Bring your N-400 receipt notice and a government-issued ID.

Step 4: Naturalization Interview

A USCIS officer interviews you in person. The interview covers your N-400 application, your background, and includes both the English reading/writing tests and the civics test. The officer may approve you on the spot, continue the case for additional documentation, or deny. Most applicants are approved at or shortly after the interview.

Step 5: Oath of Allegiance Ceremony

After interview approval, USCIS schedules your oath ceremony. At the ceremony, you renounce prior allegiances and take the Oath of Allegiance to the United States. You receive your Certificate of Naturalization at the ceremony — you are officially a U.S. citizen from that moment. You can then apply for a U.S. passport immediately.

Once you are ready, the final step in how to become a U.S. citizen is the Oath of Allegiance, a significant moment in your journey.

N-400 Processing Times in 2026

As of April 2026, USCIS processes N-400 applications in approximately 6 to 10 months, with many applicants receiving decisions in 5.5 to 6.1 months from filing to interview — the fastest processing since 2016. Processing times vary by field office. Check the USCIS processing times tool for your specific field office before filing.

Benefits of U.S. Citizenship

Permanent residence is powerful, but U.S. citizenship provides rights and protections that a green card does not:

In summary, understanding how to become a U.S. citizen provides immense benefits and opportunities that can change your life.

• Right to vote in all federal, state, and local elections
• Permanent, irrevocable status — cannot be deported (with very limited exceptions)
• Petition for more family members — immediate relatives (parents, spouse, unmarried minor children) receive immediate visa priority; adult siblings and married children have a preference category path
• U.S. passport — travel to 186+ countries visa-free
• Federal employment — many federal jobs require citizenship
• Security clearances — easier to obtain higher-level clearances
• In-state tuition and federal financial aid for education at some institutions
• Social Security benefits regardless of future residence abroad

Can You Keep Your Original Citizenship After Naturalization?

The United States does not require you to give up your prior nationality when you naturalize. Many U.S. citizens hold dual or multiple nationalities. The Oath of Allegiance contains language renouncing allegiance to other nations, but U.S. law does not legally compel you to formally renounce your original passport.

However, other countries may have different rules. Turkey, for example, allows dual citizenship for its nationals who naturalize abroad, provided they notify Turkish authorities. Germany has recently expanded dual citizenship rights for naturalized Germans. Check your original country’s laws if retaining that citizenship matters to you.

Preparing for Naturalization if You Got Your Green Card Through Work

Depending on your situation, knowing how to become a U.S. citizen can guide you through the complex immigration process.

If you came to the U.S. through an employment-based visa — whether an H-1B, L-1, EB-1A, or EB-2 NIW — and received your green card, the clock toward naturalization typically starts from the date you became an LPR, not when you first arrived in the U.S. on a work visa. Time spent in H-1B or L-1 status before getting a green card does not count toward the 5-year requirement.

Frequently Asked Questions About U.S. Naturalization

How long does U.S. naturalization take in 2026?

As of April 2026, USCIS processes N-400 in approximately 6 to 10 months total, with many applicants receiving interview notices in 5.5 to 6.1 months from filing — the fastest since 2016.

The standard path requires: 5 years as an LPR, 30 months of physical presence in the U.S. in that period, continuous U.S. residence, being at least 18 years old, good moral character, basic English ability, and passing the civics test. The 3-year path is available to those married to and living with a U.S. citizen throughout the statutory period.

What is the new naturalization civics test in 2026?

Can you have dual citizenship after U.S. naturalization?

Yes. The United States does not legally require you to renounce your original citizenship. Many naturalized U.S. citizens retain dual nationality. Whether you can retain your prior citizenship depends on the laws of your original country. Turkey and most EU countries allow dual citizenship; check your specific country’s rules before naturalizing.
