How long it will take for USCIS to update RFE

[shiva06]

I sent the evidence in reply to RFE a week ago. My status doesnt show any updates.
How long it will take for USCIS to update the status?
Do they sent any reply stating that they received evidence?

I also had my biometrics for I-485 and I-765 a week ago? What is the time period for EAD after biometrics? Is the RFE affects EAD approval?

Any info for the above questions is grately appreciated.
Thank you

There is really no precise way to know.
