What does the USCIS Response mean "reaffirming the approval of this case "

I interviewed on 24th April and my cases was sent back to review. Today I got the update as under :
“we mailed a notice to you reaffirming the approval of this case and
returned the case to the Department of State for visa processing. For more information,
please contact them directly.”
Can anyone, please guide whats next and what are the chances of my Visa Approval? What this response actually mean??
Thanx

Hi,

I hope you are doing great.

I am in the same boat, my H1B case also showing as " Department of State Sent Case to USCIS For Review", now.

how much time it took for the update from them , was it approved?

Could you please advise me?

Thanks,

Babu

Looks like consulate got confirmation for your H1B approval from USCIS so your visa should be approved unless consulate needs any further information from you.
