H4 To F1 Case process outside normal processing time

Hello Anil,

I applied H4 To F1 COS august 9th 2018( CSC). The case is out side normal processing time. They are currently doing August 15th cases. I raise the service request yesterday. I got the reply they said Expected reply by March 19.
is there any other way to follow up the case?

Thank you

There is no way to do a follow up. You can raise another Service request after March 19 though.

Hello Anil,

Thank you for your reply.
I got a email form USCIS saying

The status of this service request is:

On 02/25/2019, you contacted USCIS concerning your I-539 to notify us that you believe your case is outside of our normal processing time. Below is a summary of what we found and how the issue has been or may be resolved.

The processing of your I-539 is within our current processing time. Please see our Web site at www.uscis.gov for processing times.

I confused about with in our current processing time, My received date is august 9th 2018. The USCIS current received date for SR august 18th 2018.
California Service center ( H4 to F1 COS).

Do I need to raise another service request?
Could you please help me?

Thank you in advance.

Best Regards,

Yes, you can raise another service request if you want.

What is the time period for change of status from H4 to F1?
