Form N-400 Processing Times (September 2026): How Long Does U.S. Citizenship Take?

Quick Answer: How Long Does Form N-400 Take in 2026?

There is no single USCIS processing time for every Form N-400 application. How long naturalization takes depends largely on the USCIS field office handling your case and whether your application requires additional evidence, background review, or other case-specific processing.

USCIS reports processing times by field office. The processing time shown in the USCIS Case Processing Times tool represents how long it took that office to complete 80% of adjudicated cases during the previous six months. For Form N-400, the processing period generally runs from the date USCIS receives the application until USCIS approves or denies it.

The complete naturalization journey may take longer because an approved applicant must still attend the Oath of Allegiance ceremony before becoming a U.S. citizen.

Your timeline can change because of field-office workload, background and security checks, requests for additional evidence, interview scheduling, or case-specific review.

Form N-400 Timeline at a Glance

These stage-by-stage timeframes are planning estimates, not USCIS service standards or guarantees.

USCIS’s official processing-time tool reports how long it took a field office to complete 80% of adjudicated cases during the previous six months. Individual cases may move faster or slower.

Step-by-Step Timeline for the Form N-400 Process

The naturalization process follows several stages, but timing varies by USCIS field office and whether your case requires additional review.

Filing Form N-400

Timing: USCIS begins processing after it accepts your application.

Before filing, review the Form N-400 instructions. After USCIS accepts your application, it issues Form I-797C, Notice of Action, confirming receipt of the application.

The receipt notice includes your 13-character USCIS receipt number, which generally consists of three letters followed by 10 numbers. You can use this number to check your N-400 case status online.

Keep your receipt notice with your immigration records. You may also need information from the notice when checking processing times or contacting USCIS about your case.

Biometrics Appointment, If Required

Timing: USCIS will send an appointment notice if biometrics are required.

Form N-400 applicants generally must submit biometrics unless USCIS waives the applicable requirement. If USCIS requires you to appear at an Application Support Center (ASC), it will send an appointment notice with the date, time, and location.

Biometrics are used as part of USCIS identity verification, background checks, and security screening.

Current photo policy: Effective December 12, 2025, USCIS requires a new photograph for Form N-400 regardless of when the applicant’s previous photograph was taken. USCIS no longer applies the prior photo-reuse flexibility to N-400 photographs.

If USCIS schedules you for a biometrics appointment, follow the instructions on your appointment notice. Missing or rescheduling an appointment can affect how quickly your case moves forward.

A biometrics appointment does not mean that your citizenship interview will occur within a fixed number of days or weeks.

How Long After Biometrics Is the N-400 Interview?

USCIS does not publish a fixed waiting period between an N-400 biometrics appointment and the naturalization interview.

After biometrics, the case continues through required background, security, and eligibility review. Interview scheduling depends on your field office, workload, and whether USCIS needs additional evidence or investigation.

Completing biometrics therefore does not mean your interview will occur within a set number of weeks. Check the current N-400 processing time for your local USCIS field office and monitor your case status for the most relevant estimate.

USCIS Interview and Citizenship Test

Timing: Varies by USCIS field office and individual case.

When USCIS is ready to examine your naturalization application, it will schedule your N-400 interview and citizenship test at the USCIS field office handling your case. You will receive an appointment notice with the date, time, and location.

During the interview, a USCIS officer will:

• Review your Form N-400 for accuracy
• Verify your eligibility for naturalization
• Test your ability to read, write, and speak basic English (unless exempt). Find the sample citizenship test questions and answers.
• Administer the U.S. civics test

Interview scheduling varies by field office and individual case. Use the USCIS Case Processing Times tool for the field office handling your N-400 rather than relying on another applicant’s timeline.

Decision on Your N-400 Application

Timing: Same day to up to 120 days after the interview

After your interview, USCIS may issue a decision on the same day or continue reviewing your case.

USCIS generally has up to 120 days after your initial naturalization examination to issue a decision. You will receive the result on Form N-652, Notice of Examination Results, which will indicate whether your application is:

• Approved
• Continued (for additional review, documents, or a retest)
• Denied

If your case is continued, responding promptly to USCIS requests can help avoid further delays. If more information is needed, USCIS may send a Request for Evidence (RFE) or schedule a second interview.

Oath of Allegiance Ceremony

Timing: May occur the same day or be scheduled for a later date.

If your Form N-400 is approved, the final step is attending your Oath of Allegiance ceremony. In some USCIS field offices, applicants may take the oath on the same day as the interview, but this is not available everywhere.

If the oath ceremony does not occur the same day, USCIS will schedule it for a later date and send Form N-445 with the ceremony details.

You officially become a U.S. citizen only after taking the oath and receiving your Certificate of Naturalization.

USCIS Naturalization Investigation Policy Update — August 2026

On August 25, 2026, USCIS issued Policy Alert PA-2026-10, updating the USCIS Policy Manual to formalize the resumed use of personal investigations, also known as neighborhood investigations, under INA 335(a). The guidance applies to naturalization applications pending or filed on or after that date.

USCIS determines case by case whether an investigation is necessary or may be waived. USCIS has not published a fixed amount of additional processing time for cases that receive this review.

Applicants should therefore rely on their local field-office processing time and individual case status rather than adding a set number of weeks or months to their expected N-400 timeline.

Current N-400 Processing Times by USCIS Field Office

Form N-400 processing time can vary by USCIS field office. The table below provides a September 2026 snapshot of the USCIS-reported processing time for N-400 applications by field office.

Last checked against USCIS: September 4, 2026

USCIS defines the displayed processing time as the amount of time in which the office completed 80% of adjudicated cases during the previous six months. It is not an average.

If your Form N-400 receipt identifies the National Benefits Center, USCIS instructs N-400 applicants to use the processing time for their local field office.

USCIS makes every effort to update processing times monthly, and the displayed data are based on information that is one month old. Always verify the latest estimate using the USCIS Case Processing Times tool.

USCIS Processing Time vs. Your Actual N-400 Timeline

These measurements answer different questions and should not be treated as interchangeable.

Historical N-400 Processing Times: FY 2014–2026

USCIS also publishes historical national median processing times for Form N-400. This is a different metric from the current field-office processing time shown above.

The historical median represents the time in which USCIS completed 50% of cases during the applicable fiscal-year period, while the current field-office processing-time tool uses the 80%-completion method.

Here are the official median processing times (by USCIS) for Form N‑400:

FY2026 figures are year-to-date national median processing times through May 31, 2026, as published by USCIS. Historical processing-time data may be revised by USCIS as its records are updated.

Can You Expedite the N-400 Naturalization Process?

USCIS does not offer premium processing for Form N-400. However, an applicant may request expedited processing when the circumstances meet USCIS expedite criteria.

USCIS reviews expedite requests case by case and has discretion to approve or deny them. Applicants generally need to provide evidence supporting the reason for the request.

Situations That May Qualify for Expedited Processing

USCIS may consider circumstances including:

• Severe financial loss to a company or person, when the urgent need was not caused by the requester’s failure to file or respond within a reasonable time;
• Emergencies or urgent humanitarian reasons;
• A qualifying nonprofit organization’s request that furthers the cultural or social interests of the United States;
• Compelling U.S. government interests, including certain public-safety or national-security matters; or
• Clear USCIS error.

Meeting an expedite criterion does not guarantee faster processing. USCIS evaluates the evidence and circumstances of each request individually.

If you believe your N-400 case qualifies, follow the current USCIS instructions for submitting an expedite request.

Factors That Affect N-400 Processing Time

Several key factors can influence how long it takes USCIS to process your Form N-400 application for naturalization. Understanding these can help you better manage expectations and avoid unnecessary delays.

• USCIS workload: A high volume of applications in your local field office may increase wait times.
• Case-specific eligibility review: USCIS may need additional time if it must verify information relating to continuous residence, physical presence, marital history, good moral character, immigration history, or another naturalization requirement.
• Additional investigation: A personal or neighborhood investigation, when USCIS determines one is warranted, may add additional case review.
• Application accuracy: Errors or incomplete responses on your N-400 can result in delays or Requests for Evidence (RFEs).
• Requests for additional information: If USCIS needs more documents or clarification, your case may be paused until you respond.
• Background checks: Delays may occur if there are discrepancies in your criminal history or records that require extra investigation.

If your N-400 appears to be taking longer than expected, use the USCIS Case Processing Times tool and enter your receipt date. USCIS uses that information to determine whether your case is eligible for an inquiry.

The processing time displayed on the main page and the date when USCIS allows a case inquiry are not the same measurement. USCIS uses a higher completion threshold for determining when a case is outside normal processing and eligible for an inquiry.

How to Avoid Preventable N-400 Delays

You cannot control USCIS workload or guarantee faster N-400 processing, but you can reduce avoidable delays by making sure your application and responses are complete and timely.

• Submit a complete and accurate Form N-400: Review your answers and required evidence before filing. Missing information or documentation may lead to a rejection, Request for Evidence, or additional review.
• Respond to USCIS notices promptly: Follow the deadline and instructions on any Request for Evidence, interview notice, biometrics notice, or other USCIS correspondence.
• Attend scheduled appointments: Missing or rescheduling biometrics or your naturalization interview may affect your timeline.
• Keep your address updated: Make sure USCIS has your current mailing address so you do not miss appointment notices or requests.
• Monitor your case: Use your USCIS online account or receipt number to check case status and review the processing time for your local field office.
• Request expedited processing only when appropriate: Form N-400 does not have premium processing. An expedite request is discretionary and should be supported by evidence showing that your circumstances meet USCIS criteria.
