N-400 Processing Time by Field Office

N-400 processing time varies by USCIS field office, case history, and the steps required before the naturalization oath ceremony. As of August 18, 2026, published estimates for standard naturalization applications were 14.5 months in Newark, 13.5 months in Philadelphia, and 14 months in Houston, based on data drawn from the USCIS Case Processing Times tool.

These estimates show how long USCIS took to complete most recently adjudicated cases. They cannot predict your completion date. Below, we compare the three offices, explain each stage of the Form N-400 timeline, and discuss what you can do if your application appears delayed.

Key takeaways on N-400 wait times

• The current N-400 processing time is about 13.5 to 14.5 months at the three offices covered here, based on figures checked August 18, 2026.
• Newark has the longest published estimate of the three at 14.5 months. Philadelphia has the shortest at 13.5 months.
• A posted estimate is a reference point based on completed cases, not a deadline or promise for your application.
• Biometrics, interviews, evidence requests, and appointment availability can affect an individual timeline.
• Approval of Form N-400 does not make an applicant a citizen. According to USCIS naturalization process guidance, citizenship begins after the applicant takes the Oath of Allegiance.

Current N-400 processing time by field office

USCIS describes its displayed processing time as the period in which it completed 80% of adjudicated cases during the previous six months. The measurement runs from receipt of the application through approval or denial, and USCIS updates the information monthly. The agency cautions that these figures are reference points rather than individual predictions, as explained in its processing-time methodology.

Newark, New Jersey field office

The Newark estimate was 14.5 months on the date checked. If your receipt notice lists the National Benefits Center, USCIS instructs N-400 applicants to consult the estimate for their local field office. You can use the agency's office locator if you are unsure which location applies, and our New Jersey immigration guidance provides broader state-specific context.

Philadelphia, Pennsylvania field office

Philadelphia reported an estimate of 13.5 months. That does not mean every application will finish sooner than a Newark or Houston case. An individual application may move above or below the published figure because of its history, required evidence, and scheduling needs.

Houston, Texas field office

Houston's published estimate was 14 months. Applicants should use the office shown by USCIS for their case rather than choosing an estimate based only on where they mailed or submitted the form.

So, what is the current wait time for naturalization? For the three offices compared here, the published standard N-400 estimates range from 13.5 to 14.5 months. We retrieved these figures on August 18, 2026, using the USCIS processing-time source for Form N-400 and the Newark, Philadelphia, and Houston field offices. Because USCIS updates its data, check the current N-400 office estimate again before making plans.

N-400 timeline from filing to oath ceremony

Every naturalization case has its own sequence. Some steps overlap, USCIS may reuse existing biometrics, and an applicant may receive a request for more information before a decision.

Receipt notice and initial review

After USCIS accepts Form N-400, it issues a receipt notice containing a receipt number. Keep that notice accessible. The number allows you to follow the application through USCIS case-management tools and may be needed if you later submit an inquiry.

During its review, USCIS considers the form, supporting records, and information already available in government files. A notice requesting missing evidence can add another step.

Biometrics, if required

USCIS will send an appointment notice if new fingerprints, a photograph, or a signature are needed. Existing biometrics may sometimes be reused, so the absence of a new appointment does not necessarily indicate a problem. The agency explains the appointment process in its naturalization overview.

Follow the instructions on any notice you receive. Missing an appointment or responding late may affect the timeline.

Interview and naturalization test

At the interview, a USCIS officer reviews your application and asks questions about your background. Most applicants also complete English and civics testing unless an exemption or waiver applies.

Bring the documents requested in your appointment notice. USCIS instructs applicants to bring their Permanent Resident Card, identification, and passports or travel documents recording absences since becoming a permanent resident, along with any other case-specific materials requested.

Decision and oath ceremony

USCIS may approve the application, continue it while requesting more information, or deny it. When an application is approved, the applicant must still attend a naturalization ceremony and take the Oath of Allegiance before becoming a citizen.

The oath may occur on the interview date or later, depending on the office and the case. For that reason, the published processing time and your final oath date are not always identical.

Why N-400 processing times vary

Field-office workload and appointment availability

USCIS identifies application volume, workload, staffing allocations, and operational changes as factors that may affect completion times. Local interview and ceremony capacity may influence scheduling as well. Our discussion of why immigration cases can take longer offers more context for families facing an uncertain wait.

Requests for evidence and missing information

A Request for Evidence gives an applicant a chance to provide information USCIS considers necessary. USCIS includes applicant response time in its processing-time calculation, according to the agency's processing-times FAQ.

Read the entire notice, confirm the deadline, and submit a complete response through an accepted delivery method. A confusing or legally significant request may warrant attorney review.

Background, residence, travel, tax, or criminal-history issues

Naturalization requires USCIS to examine eligibility under the applicable law. Residence and travel history, tax records, prior immigration matters, arrests, charges, or convictions may require closer review depending on the facts.

These issues do not lead to the same outcome in every case. And a longer wait, by itself, does not mean USCIS plans to deny the application.

How to reduce preventable N-400 delays

Review the form and supporting records carefully

Check dates, addresses, employment history, travel, marital information, and answers about prior legal or immigration matters before filing. Compare the completed form with your records and explain inconsistencies where appropriate.

For a complicated history, personalized review may help identify questions before submission. Our immigration law services include case-specific guidance for individuals and families navigating naturalization and other immigration matters.

Monitor notices and keep contact details current

Check your mail and online account regularly. If you move, update your address through the appropriate USCIS process rather than relying only on mail forwarding. USCIS encourages applicants to keep their address current and provides an online change-of-address option.

Respond to each notice by the stated deadline. Avoid submitting an unnecessary duplicate application or making an expedite request without a supported basis.

Prepare for the interview and test

Review your filed N-400 before the interview, gather the documents listed in the notice, and study through official USCIS materials. Preparation cannot guarantee faster adjudication, but it can reduce avoidable confusion on the appointment date.

Checking your case, delayed applications, and travel

How to check N-400 case status

Use the USCIS Case Status Online tool and enter the receipt number from your notice. USCIS describes this identifier as three letters followed by 10 numbers and advises users to omit dashes when entering it.

An online account may also provide notices, case history, and automatic updates. The public status tool and account information may not explain every period without visible activity.

What if the case exceeds the posted time?

Start with the current processing-time page because estimates and inquiry eligibility can change. USCIS provides a case inquiry date based on a separate measure for completed cases, so passing the displayed 80% estimate does not automatically establish that an inquiry is available.

Enter your receipt date in the USCIS tool and follow the current instructions. If the agency indicates that you may ask about the case, use its outside-normal-processing-time inquiry.

Can I travel while N-400 is pending?

A pending Form N-400 does not create a blanket prohibition on international travel. But whether a particular trip is advisable can depend on valid permanent-resident documentation, trip length, continuous residence, physical presence, and other case facts.

USCIS requires applicants to disclose travel history and explains that extended absences can affect naturalization eligibility in the Form N-400 instructions. Seek case-specific legal advice before extended travel or a trip involving documentation or residence concerns.

Frequently asked questions

How long will it take to process an N-400 application in 2026?

Check the field-office table above for Newark, Philadelphia, and Houston estimates verified on August 18, 2026. Your application may finish sooner or later because USCIS figures describe recently completed cases, not your future completion date.

Are N-400 applications processed in the order received?

Receipt date matters, but cases do not always finish in strict filing order. Workload, appointments, evidence requests, background checks, and case-specific review can cause later-filed applications to finish first.

Does premium processing apply to Form N-400?

No. Form N-400 is not listed among the benefit requests eligible for premium processing. USCIS currently limits the service to designated classifications filed through specific forms, as shown on its premium processing eligibility page.
