N-400 Processing Time: How Long for Citizenship in 2026

Becoming a United States citizen is one of the most important steps a green card holder can take, and for most applicants, the process starts with Form N-400, the Application for Naturalization. Understanding the current N-400 processing time is essential for planning around work, travel, and family decisions. If you are preparing to file or have already submitted your application, an experienced immigration lawyer can help you navigate the timeline, avoid preventable delays, and respond to any issues that arise along the way. A Citizenship & Naturalization Lawyer at Brooks Law Firm can also review your eligibility, prepare your application, and guide you through the interview and civics test.

As of late 2026, USCIS reports that N-400 processing times range from roughly 8 to 17.5 months for 80% of recently completed cases, though the full range across all field offices stretches from about 7 months at the fastest offices to over 20 months at the slowest. The timeline depends heavily on which USCIS field office handles your case.

How Long Does the N-400 Take in 2026?

There is no single answer to how long the N-400 takes, because the timeline is tied almost entirely to the field office adjudicating your application. Nationally, the average processing time falls in the range of roughly 10 to 14 months from filing to oath ceremony, but individual offices operate on very different schedules.

Some of the fastest offices in the country have completed cases in as few as 3 months. Others, particularly in major metropolitan areas with larger caseloads, routinely take 15 months or longer. The Boston field office, which handles naturalization applications for much of Massachusetts, currently reports a processing range of approximately 13.5 to 15.5 months, placing it well above the national average.

A filing surge in the fall of 2025 pushed the national N-400 backlog from roughly 537,000 pending cases in September 2025 to approximately 647,000 by February 2026. While USCIS has been working to bring that number down, the ripple effect on scheduling and interview wait times is still being felt at many field offices.

US Citizenship Processing Time 2026: What Each Stage Looks Like

The US citizenship processing time in 2026 can be broken down into several stages, each with its own typical wait. These ranges are approximations based on reported USCIS data and may vary depending on your field office and individual circumstances.

• Receipt notice: 2 to 4 weeks after USCIS receives your application. You will receive a notice with your 13-character receipt number, which you can use to check your case status online.
• Biometrics appointment: 4 to 8 weeks after filing. USCIS collects your fingerprints, photograph, and signature at an Application Support Center. The visit itself usually takes less than 20 minutes, but missing or rescheduling the appointment can delay your case.
• Background and security checks: 2 to 6 months. USCIS and the FBI verify your identity, criminal history, and immigration record. Most checks clear within a few weeks, but complications such as common-name matches, prior arrests, or extensive foreign travel can extend this stage considerably.
• Interview scheduling and interview: This is where the biggest variation occurs. Some offices schedule interviews within weeks of the background check clearing, while others face a months-long backlog. At the interview, a USCIS officer reviews your application, tests your ability to read, write, and speak English, and administers the civics test (10 questions drawn from a pool of 100, with a passing score of 6 correct).
• Decision: Many applicants receive a decision the same day as the interview. In some cases, USCIS may continue the case to request additional evidence or complete further review.
• Oath ceremony: Typically 1 to 4 weeks after approval, though the timing varies by location. You officially become a United States citizen when you take the Oath of Allegiance.

Naturalization Timeline: From Eligibility to Filing

The naturalization timeline actually begins well before you file Form N-400. To be eligible, you must meet several requirements established by the Immigration and Nationality Act, and the clock toward filing starts on the date USCIS recorded you as a lawful permanent resident.

The general eligibility requirements include:

• You must be at least 18 years old at the time you file
• You must have been a lawful permanent resident for at least 5 years (or 3 years if you received your green card through marriage to a U.S. citizen and remain married and living together)
• You must have maintained continuous residence in the United States during that period
• You must have been physically present in the United States for at least 30 months out of the 5-year period (or 18 months out of the 3-year period for marriage-based applicants)
• You must have lived in the state or USCIS district where you file for at least 3 months before filing
• You must demonstrate good moral character during the statutory period (5 years, or 3 years for marriage-based applicants) and through the oath ceremony
• You must be able to read, write, and speak basic English
• You must pass a test on U.S. civics and government

USCIS allows applicants to file Form N-400 up to 90 days before reaching the 5-year (or 3-year) anniversary of their permanent residence. That early filing window can shave nearly three months off the total wait, which is worth considering given how long some field offices are currently taking to schedule interviews.

If you received your green card through marriage, you may want to review our guide on how to get a green card through marriage to confirm that your original application was properly filed, since issues in the underlying case can sometimes surface during the naturalization review.

N-400 Interview Wait Time: The Stage Where Most Applicants Wait the Longest

The N-400 interview wait time is typically the most unpredictable part of the process. After your background check clears, your case enters the interview scheduling queue at your local field office, and how long you wait depends on the number of officers available and how many cases are ahead of yours.

At faster offices, applicants may receive an interview notice within 3 to 5 months of filing. At busier offices, including Boston, the interview may not be scheduled until 10 to 12 months or more after the application was submitted.

During the interview, a USCIS officer will:

• Verify the information on your N-400 application under oath
• Review your travel history, employment, and any arrests or legal issues
• Test your English reading, writing, and speaking ability
• Administer the civics test (6 out of 10 correct answers to pass)
• Make a decision or continue the case for additional review

Applicants who are 65 or older and have lived in the United States as permanent residents for at least 20 years qualify for a simplified civics test drawn from a smaller pool of 20 designated questions, administered in their native language. Applicants 50 or older with 20 years of permanent residence, or 55 or older with 15 years, are exempt from the English language requirement and may take the standard civics test in their native language.

If you do not pass the English or civics test on your first attempt, USCIS will schedule a second opportunity within 60 to 90 days of the initial interview.

USCIS Citizenship Delays: Why Your Case May Be Taking Longer

USCIS citizenship delays affect applicants for a range of reasons, some within your control and some not. Understanding the most common causes can help you avoid preventable setbacks and recognize when it may be time to take action.

Background check complications. The FBI background check is routine, but it can take longer when an applicant has a common name that generates multiple database matches, a history of arrests (even if charges were dropped or dismissed), or significant travel to countries that require additional security screening. There is no way to expedite a pending background check, though a congressional inquiry can sometimes help identify whether a case is stuck or simply in the normal queue.

Requests for Evidence (RFE). If USCIS needs additional documentation or clarification, it will issue an RFE, and your case pauses until you respond. Common triggers include missing tax transcripts, questions about extended travel abroad, and discrepancies between the N-400 and prior immigration applications. Responding promptly and completely is critical, because an incomplete or late response can lead to a denial.

Application errors. Filing an incomplete N-400 or submitting the wrong form edition can result in a rejection before your case even enters the processing queue. Online filing tends to reduce these errors because the system flags missing fields before submission.

Field office caseload. The single biggest factor in total processing time is the capacity of your local field office. An office with a high volume of pending cases and limited staffing will take longer to schedule interviews and administer oath ceremonies, regardless of how straightforward your individual case may be.

Travel while the case is pending. Filing Form N-400 does not restrict your ability to travel, but extended absences can affect your continuous residence and physical presence. A trip lasting more than six months may raise a presumption that you broke continuous residence, and USCIS may ask about your travel history at the interview.

The fall 2025 filing surge. A significant increase in N-400 filings in October and November 2025, likely driven by the approaching election cycle and concerns about potential policy changes, created a backlog that continues to affect scheduling at many offices.

How Long Does Naturalization Take for Green Card Holders in Massachusetts?

For green card holders in Massachusetts, the question of how long naturalization takes comes with a specific answer: the Boston field office currently reports a processing range of approximately 13.5 to 15.5 months. That places it well above the national average and means that many Massachusetts applicants should plan for a total timeline of roughly 14 to 16 months from filing to oath ceremony.

USCIS considers a case to be outside normal processing time if it was filed on or before June 28, 2025 and remains pending. If your case falls into that category, you may submit a service request through the USCIS processing time tool or contact the USCIS Contact Center at 1-800-375-5283 to request a status update.

Massachusetts applicants should also be aware of a few practical details:

• Your N-400 interview will most likely take place at the USCIS Boston field office, though USCIS has the authority to schedule interviews at other offices as part of its national workload-balancing efforts.
• Oath ceremonies in Massachusetts are held both by USCIS (administrative ceremonies) and by federal courts. The timing of your ceremony depends on which type you are assigned and the scheduling availability at that time.
• If you have a criminal record in Massachusetts, including matters resolved through a continuance without a finding (CWOF), it is important to discuss this with an attorney before filing. A CWOF is generally treated as a conviction for immigration purposes under INA §101(a)(48)(A), and failing to disclose it on your N-400 can result in a denial for lack of good moral character.

If you originally obtained your green card through asylum, the naturalization timeline may be shorter than you expect. Your green card date is rolled back by one year under the law, which means you may be eligible to file approximately four years after your green card approval rather than five. For more detail, read our article on getting a green card after asylum.

What the N-400 Costs in 2026

The filing fee for Form N-400 is currently $710 when filed online and $760 when filed by paper. That single fee covers both the application review and the biometrics appointment, which USCIS combined into one charge in April 2024. There is no separate biometrics fee.

A reduced fee of $380 is available for applicants who meet certain income thresholds, and a full fee waiver is available through Form I-912 for applicants with qualifying low incomes or who receive certain means-tested public benefits. Both the reduced fee and the fee waiver currently require filing by paper.

One important development to watch: in June 2026, the Department of Homeland Security proposed raising the N-400 fee to $1,330 for paper filers and $1,280 for online filers, a 75 to 80 percent increase. The proposal also included the elimination of fee waivers and reduced fees for naturalization applicants. The public comment period has closed, but as of this writing, the final rule has not been published and the current fees remain in effect. For green card holders who are already eligible or approaching eligibility, filing at the current fee avoids the risk of a higher cost later. For a detailed breakdown, read our guide on the citizenship application fee.

How to Check Your N-400 Case Status

You can track your case using the receipt number USCIS assigned when it accepted your filing. There are two main ways to check:

• Online: Visit the USCIS Case Status tool and enter your 13-character receipt number.
• By phone: Call the USCIS Contact Center at 1-800-375-5283.

If your case has been pending longer than the posted processing time for your field office, you can submit a service request through the USCIS website. USCIS generally responds within 30 days, typically with a status update or a notice that the case remains within normal processing parameters.
