Searching for N-400 processing time by state can be frustrating because two applicants living in the same state may face different waits. USCIS generally publishes naturalization processing figures by field office, not as one statewide average. That distinction matters in places such as California, Florida, New York, and Texas, where several offices handle different local areas.
The comparisons below provide a dated 2026 reference, followed by a practical way to find the estimate that actually applies to your application. Published figures change, so use the USCIS Case Processing Times tool for the latest number before making plans.
2026 N-400 Processing Times: A Field Office Comparison
An August 2026 field-office comparison published by Immigration Direct reported the following N-400 completion times. These are historical snapshots, not live October 2026 estimates or promises of how long a newly filed case will take. Each number is in months. USCIS may have published newer figures since that comparison.
California and the West
California: Los Angeles, 9.5; San Francisco, 12; Sacramento, 14; San Diego, 12.5; San Jose, 12.5. A California resident should not assume the Los Angeles figure applies statewide.
Washington: Seattle, 11; Spokane, 10. Oregon: Portland, 12. Arizona: Phoenix, 10.5; Tucson, 11.5. Colorado: Denver, 12.5. Nevada: Las Vegas, 11.5; Reno, 10.
New York and the Northeast
New York: New York City, 9.5; Brooklyn, 10; Queens, 8; Albany, 8.5; Buffalo, 12.5. These differences show why choosing the correct office is more useful than searching for a New York statewide average.
New Jersey: Newark, 10; Cranbury, 8.5; Mount Laurel, 8.5. Massachusetts: Boston, 13; Lawrence, 17. Pennsylvania: Philadelphia, 10; Pittsburgh, 10.5. Connecticut: Hartford, 10.
Texas, Florida, and the South
Texas: Dallas, 11.5; Houston, 11.5; San Antonio, 11; El Paso, 11.5. Florida: Miami, 7.5; Hialeah, 7; Orlando, 11; Tampa, 12; Jacksonville, 13.5; West Palm Beach, 9.
Georgia: Atlanta, 11.5. North Carolina: Charlotte, 10; Raleigh, 10.5. Alabama: Montgomery, 8.5. South Carolina: Charleston, 10.5; Greer, 9. Virginia: Norfolk, 8.5.
Midwest and Other Locations
Illinois: Chicago, 9.5. Michigan: Detroit, 11. Minnesota: Minneapolis–St. Paul, 13.5. Ohio: Cincinnati, 7.5; Cleveland, 8.5; Columbus, 9. Missouri: Kansas City, 11; St. Louis, 11. Puerto Rico: San Juan, 7.5.
These examples cover selected USCIS offices, not every location. Treat them as a historical comparison showing geographic variation. For your current naturalization timeline, check the office-specific USCIS result rather than copying an older figure into a personal deadline.
How to Find Your Correct USCIS Field Office
Start with the USCIS Field Office Locator and enter your home ZIP code. An office in your state is not necessarily the office assigned to your address. Then open the official USCIS Case Processing Times page, choose Form N-400, select the applicable category and field office, and read the displayed estimate.
If your receipt notice identifies the National Benefits Center, USCIS instructs N-400 applicants to use the local field office for processing-time purposes. If USCIS transfers your case, follow its guidance and check the office handling it. Your interview notice, when issued, gives the actual appointment location.
For example, someone living near Miami should not automatically use the Tampa estimate merely because both offices are in Florida. Confirm the office serving the applicant’s ZIP code first, then compare the published number with the N-400 receipt date.
What the USCIS Processing Time Actually Measures
USCIS explains that its displayed processing time represents the period within which it completed 80% of cases adjudicated during the previous six months. It measures elapsed time from application receipt to the approval or denial decision. It is not the average waiting time, a personalized prediction, or a deadline by which USCIS must finish your application.
This also explains why USCIS field office wait times may change from month to month. Recent completed cases, staffing, application volume, background reviews, and requests for evidence can all affect the published result. An applicant might finish well before the reported time or remain pending longer.
Be careful with national historical medians, too. A nationwide median measures a different portion of completed cases and should not be compared directly with the field-office 80th-percentile figure.
From Filing to Oath: Where the Waiting Happens
The N-400 process can include USCIS receipt and initial review, biometrics or notice of biometrics reuse, background checks, an interview with English and civics testing when required, a decision, and the Oath of Allegiance. Interview availability and additional case review can influence the schedule.
An approved applicant does not become a U.S. citizen until taking the oath. Because the reported processing period ends at adjudication, a later oath ceremony can extend the overall journey beyond the posted N-400 figure. For preparation, see our N-400 application checklist and citizenship interview preparation guide.
How to Track Your N-400 Status and Recognize a Delay
Use the USCIS Case Status Online tool or your USCIS online account to view notices and case updates. The receipt number is the key identifier for case-status searches. Check messages and mailed notices instead of relying solely on an estimated completion date inside an account.
If a case seems slow, use USCIS’s case inquiry date tool. The date when you become eligible to ask about a pending case is not necessarily the same as the published 80% processing figure. USCIS advises checking the inquiry eligibility date before sending an outside-normal-processing-times request.
Keep your mailing address updated with USCIS after moving, respond promptly to evidence requests, and attend scheduled appointments. A move can change the relevant local office and may affect scheduling. Our naturalization eligibility requirements guide can help readers review the underlying filing rules while their applications are pending.
Frequently Asked Questions
Does every applicant in one state have the same N-400 processing time?
No. USCIS uses field-office figures, and some states have multiple offices with different caseloads. Identify the office connected to your address or current case assignment.
Why does my receipt show the National Benefits Center?
That can be normal. USCIS says N-400 applicants whose receipts list the National Benefits Center should consult processing times for their local field office.
Can I submit an inquiry when my case passes the posted processing time?
Not automatically. Check the USCIS case inquiry date for your form, office, and receipt date. That tool indicates when an outside-normal-processing-times inquiry is appropriate.
Does approval mean my citizenship process is finished?
No. Unless an oath ceremony occurs at the same appointment, you must wait for your oath notice and take the Oath of Allegiance before becoming a citizen.
Making Sense of Your Local Wait
The most useful answer to an N-400 processing time by state search is usually an office-specific answer. Use dated comparisons to understand how widely waits can differ, but rely on USCIS’s current field-office estimate, your receipt date, and your individual N-400 status for decisions. That gives you a clearer picture than any single nationwide timeline.
