EAD (WorkPermit)

Dear Friends,

I’ve been a silent reader for several months now. I have to say that’s forum has been of great help, it’s so nice to see people that’s struggling like me getting their cards.
But I would like get some advice from someone that have been in the same boat that I’m right now.
Let me Share my timeline with you first:

I’m spouse of a Green Card holder and I have a F1 visa until I get my EAD. I live in Miami and my case has been process in the NBC.

I-130 – 07/17/19

I-485 – 08/05/19

I765 – 08/05/19

I131 – 08/05/19

Biometrics – 09/13/19

Biometrics applied to I765 – 09/27/19

Biometrics applied to I131 – 03/05/21

Case Inquiry for outside processing time – 03/20/21 (I should expect an answer until 04/11/20)
I had no answer, so I called for the first time and they told me that I should expect a month after open case inquiry before I call again.

04/21/20 – I called again and they said that they had no answer, so I had to open a second case inquiry.

In the next day I check the portal and my case inquiry was closed.

04/23/20 – I called for the third time, an a very polite man picks up the phone and said a letter was sent to me and he affirm that my case was on hold waiting for further evidence since 03/13. Please note that this information was never given to me in none of my calls or chat with Ema.

Las Saturday I received a letter requesting evidence of affidavit that I sent 04/27.

My questions are:
Normally how long after we send the evidence it takes to have the case approve?

Is there anything that I can do to accelerate the process? Do you believe I can open another case inquiry once that they have the evidence they were seeking for?

I would appreciate any information or help.

Thanks in advance,
