All I-129F (K-1/K-2) applications are processed at the California Service Center (receipt numbers starting with "WAC") no matter where you mailed your form. You can read more about service centers in our Blog post.
Application flow
All cases start in the Case Received status. Approximately 6% of applications get Rejected within a few weeks due to improper filing. Of the remaning cases, about 65% of cases get directly Approved and a small minority of them (3%) get directly Denied. The rest of the applications receive a Request for Evidence. Once USCIS receives the additional evidence from the applicant, their status changes to Request for Evidence Received. After that, about 18% of cases get Approved, while 8% get Denied, usually within a few weeks.

What does the current case backlog look like?
This graph shows the status of all I-129F cases received by USCIS in the last 2 years.
The backlog helps us understand the big picture. For example, we can see that USCIS generally processes cases in the order they were received.
Newer cases are shown on the right side of the graph. They mostly have the Case Received status. We can also see that incorrectly filed forms are usually Rejected by USCIS soon after they are received. On the other side of the graph, the old cases have mostly all been processed - either Approved, Denied, or Rejected.
Near the middle of the graph, you see that USCIS is actively working on cases - turning months from light blues into greens and yellows. Once USCIS starts working on a month, many cases are quickly Approved, while others take longer due to a variety of reasons, such as a Request for Evidence (see our Blog post about RFEs).
While the backlog chart is a rich source of data, it isn't able to answer all questions. To see how fast USCIS is processing cases and to see exactly what month they are working on, we need to look at the graphs below.
How many cases is USCIS processing?
At the beginning of January 2023, USCIS greatly increased its processing rate, leading to a dramatic reduction in wait times. I-129F processing times hit a low in June 2024 when the median processing time was just under 3 months. Since then wait times have steadily risen and are still increasing.
