Form N-400 processing time
Application for Naturalization
For a current result, match your category and location in the official USCIS tool. A form number alone does not identify the processing time or establish when you may inquire.
Bring these details to USCIS
- Your form number and the category that matches your filing.
- The office or service-center option requested by the current tool. Keep an unknown location unknown until you confirm it.
- The received date from your receipt notice, for the official inquiry tool.
Record the day you checked, the options you selected and the answer USCIS actually gave. Reopen the tool before acting on an earlier inquiry date; it can change. This page has no verified current category-and-location result.

Each row covers only its named filing basis. FY2024 is partial. These figures are historical context, not a live waiting-time estimate or a forecast for your case.
| Filing basis | FY2016 | FY2017 | FY2018 | FY2019 | FY2020 | FY2021 | FY2022 | FY2023 | FY2024* |

National median months from receipt to completion across all USCIS offices. FY2024 reflects Oct 1, 2023 – Jan 31, 2024 (partial year). Historical fiscal-year medians use a different methodology than the live USCIS processing-times tool and are not directly comparable. Source: USCIS historical factsheet. Existing source record: March 5, 2024. These figures have not been refreshed as current processing data.
Questions about this page
How do I check the current processing time for N-400?
Use the official USCIS processing-times tool and select the form, applicable category, and office or service-center option it requests. This page does not hold a verified current result for that combination.
When can I ask USCIS about my N-400?
Enter your receipt date in the current official inquiry tool after choosing the applicable form, category and location. Follow its answer. A past result or a historical statistic does not establish permission to inquire today.
Does the historical median predict my decision date?
No. Historical fiscal-year medians describe completed cases in the listed category and period. They do not predict the date or outcome of a pending case.
Legacy form record reviewed: 2026-06-12. That date does not verify a current processing time. Method: USCIS processing-data explanation (May 5, 2022).
