H4 EAD status -Correspondence Was Received And USCIS Is Reviewing It

I applied for renewal of my H4 EAD in OCT 2020 as only my EAD was expiring in Feb 2021. In June 2021 my H4 expired so my spouse applied for H1 renewal along with my H4 at this time we didn’t again apply for H4 Ead as we already had one on renewal process…

  1. my H4 got approved in Sept 2021 but still no change in my EAD that was propbably because it was filed for renewal based on my previous H4…

  2. Oct 15th 2021 i got a RFE in which USCIS requested for my new H4 and my spouse H1 for which i reverted immediately in 2 days

  3. Oct 25th USCIS updated the status to Received response and USCIS is reviewing it.

  4. Nov 15th again my status changed to Correspondence Was Received And USCIS Is Reviewing It.

Has anyone experienced this and how soon after this did USCIS approve their case?

We are in a very bad situation frustrated and loosing here dono how long further should we wait for our case to get approved.
