I had an Interview on Feb 22 and done with eight weeks.
Did you consult with your work attorneys? Also in this post it appears green slip appears to be a refusal. Yours likely isn’t since Vo said they need additional info, but typically they keep passport in such situations.
Does your green slip read the same? If so, you won’t hear back.
