H1b Extension due date for maxout case

[Simran Ji]

Hi,

Below is my current situation :
I am in my 6th year of H1B with maxout date as Aug 4, 2019 and current i94 is expiring on Aug 14, 2019

My PERM was filed in my 6th year and both PERM and I-140 are approved as if today. My H1b extension case is yet to be submitted to USCIS.

What is my due date for filing H1b Extension, is it Aug 4th i.e. maxout date or Aug 14, i94 expiration date?

What are my options if my employer fails to file the extension before the due date?

 

Regards
