Introduction to Case Processing Times

USCIS displays case processing times for select forms and locations to let people know how long it generally takes to process benefit requests and when they can submit a service request for a case that is “outside normal processing time.” We update case processing times on the website monthly with the latest available data.

This webpage provides information on how to read and interpret the processing times on the website. It also provides details on the two different methodologies that we use to calculate processing times.

Where can I find my form number and the office that is processing my case?

Your receipt notice has key information you will need to determine your processing time.

Sections of a receipt notice with the following key information highlighted: 1. Form Type or Case Type; 2. Receipt Number; 3. Receipt Date; 4. USCIS Office.


If the “USCIS Office” is the National Benefits Center (NBC) and you have filed an employment-based or family-based Form I-485, Form N-400, or Form N-600, you should check processing times for your local field office.



Example: Estimated time range - 6.5 Months to 12 Months, Form type - Application for Naturalization, Receipt date for a case inquiry - December 16, 2019

Estimated time range: This column lists case processing times as a range for select forms and locations. The lower value of the range is the time it took us to adjudicate 50% of our cases. The upper value of the range is the time it took us to complete 93% of our cases. See below for a description of how these ranges are calculated.

Form type: A description of the sub-type (for example, Form N-400, Application for Naturalization).

Receipt date for a case inquiry: The receipt date indicates when a person can submit a service request for a case that is “outside normal processing time.” Someone who has a receipt date before the “Receipt date for a case inquiry” can submit such a request online.

You can also view processing times for the Administrative Appeals Office and international offices. You can also find processing times for Form I-765, Application for Employment Authorization.

Methodologies for Calculating Processing Times

We use two methodologies for calculating processing times: cycle time (our old method) and processing time (our new method).

We have used the old method (cycle time) to measure processing time since 2009. As described in more detail below, it relies on aggregate pending and receipt counts, not individual case processing information. In 2018, we began using actual case record information for greater accuracy of the information we posted on our website. Listed below are the forms that we currently post processing times for and the methodology associated with each form.

We use the cycle time methodology for Forms:

  • I-129
  • I-129CW
  • I-129F
  • I-130
  • I-131
  • I-212
  • I-360
  • I-539
  • I-600
  • I-600A
  • I-601
  • I-601A
  • I-612
  • I-730
  • I-800
  • I-800A
  • I-821
  • I-918
  • I-929
  • N-565

We use the processing time methodology for Forms:

  • I-90
  • I-102
  • I-140
  • I-407
  • I-485
  • I-526
  • I-751
  • I-765
  • I-765V
  • I-817
  • I-821D
  • I-824
  • I-829
  • I-914
  • I-924
  • N-400
  • N-600
  • N-600K

We are working to move forms that use the cycle time methodology to the processing time methodology.

Cycle Time Methodology

Cycle time is the number of previous months of receipts it takes to equal the current month’s pending receipt volume.

For example, if a specific form has 500 applications pending for the month of April 2020 and received 200 receipts in February 2020 and 300 receipts in March 2020, then the cycle time for this form in April 2020 is 2 months (200 + 300 = 500 pending applications). This is defined as the lower range value. The upper range value is normally the lower range value x 1.3.

For example, if the cycle time is 2 months, then the upper range value would be 2 months x 1.3 = 2.6 months (rounded up to 3 months).

In this example, the range posted on the website for this form for April 2020 would be 2 Months to 3 Months.

Processing Time Methodology

Processing time is the number of months that elapse between the date we receive an application, petition, or request and the date we complete the application, petition, or request (that is, when we approved or denied it) for all cases for a specific form for the latest completed 6 months.

For example, if USCIS received a Form I-914 application on Feb. 23, 2020 and completed the application on April 5, 2020, then the processing time for that specific application is 41 days. We make this calculation for every Form I-914 application that we complete in a specific period (in our example here, this would be April 2020). We then calculate the median value (or 50th percentile) for all Form I-914 applications we completed from November 2019 to April 2020 inclusive, which represents the lower range value. We also calculate the 93rd percentile, which represents the upper range value (or the “Receipt date for a case inquiry”). For example, for April 2020 for
Form I-914, our processing times ranged from 19.5 months to 26.5 months. This means that we adjudicated half our cases in 19.5 months or less (the 50% mark) and 93% of our applications in under 26.5 months. We completed the remaining 7% over 26.5 months.

In this example, the range posted on the website for Form I-914 for April 2020 would be 19.5 Months to 26.5 Months.

Why Use the Processing Time Methodology?

The processing time methodology provides the most precise and up-to-date information available because it is based on the most recently completed cases. The cycle time methodology provides an estimate of case processing times, using slightly older data.

Historical Processing Times

We provide a history of our median historical processing times for select forms. This information includes the cumulative median processing time by fiscal year (Oct. 1-Sept. 30), using the processing time methodology.

Additional Note for I-485, Application to Register Permanent Residence or Adjust Status

Visa regressed I-485s and revoked petitions or applications are excluded. You can find additional information on visa retrogression on our website.
