PERM Overall timeline 2018

[amore2]

My perm was filed on 15th Sept 2018, my H1 is getting Maxout on 19 March 2019.
What is the possibility that My perm gets approved before my Visa max out.
As soon as my perm gets approved what is the immediate step which I need to take either apply for i140 or apply for extension.

Just hope PERM doesn't get audited. Otherwise I think you have a good chance IMO.
