What are the various icert status possible for H1B?


My H1B has gone into RFE, and am awaiting next update from them. I just checked my status on the icert site and see it as “certiified”. What does this status mean, and where I am in the workflow?

Can any body point me in the right direction please on this? I had received the RFE notice via my employer on around 16th Aug, and I have already submitted all required documents back to my employer. My LCA status now reads on icert site a ‘certified’. What does this mean?
