receipt date for case inquiry i-130 filed for Bringing Canadian born child to US

[SN@5127 7]

I have question if someone can shed some light on this:

Regardless of how long it will take for my 1-130 application (i.e 5 years - 10 years or 20 years) I want to know why this receipt date for case inquiry in a specific service center keeps floating. Such as I see it one month earlier it was Oct 2016, one month later instead of going forward it went backward to Sept 09, 2016. If I ever ask a question; the reader comes back with vanilla answer "Oh you should not worry about (timeline) of your case, it will take XYZ blah years". The fact is that I am not worried about how long it will take; I just want to understand  their logic of back and forth dates scenario. If you have knowledgeable advice please advise. 

 

Many many thanks,

Sam

The receipt date for a case enquiry is based on the longest part of the average time per type of petition. It can change in a non linear fashion because processing times speed up or slow down depending on unanticipated changes to the speed at which they can deal with existing cases (including things like staffing changes), on the new workload coming in and how those cases get prioritized vis-a-vis existing cases, and on how cases get reallocated among service centers to split the load among them. And probably other things too. For it to go one month down for every actual month in real time would basically require that they manage to process just about exactly the same amount of the same types of petitions every month, and with the same amount of new workload coming in as those processed going out, and the real world just doesn’t work like that.

Here is the official explanation from USCIS -- https://egov.uscis.gov/processing-times/more-info

 

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. [...]

 

We use the cycle time methodology for Forms: [...]  I-130  [...]

 

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. [...]

 

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.
