L1B to L1A COS in progress, I-94 expiring soon

Hi,

I’ll max-out with my current L1B by Dec15th,2018 and both L1B and I-94 are expiring on the same day. My employer is applying for L1A COS very soon.

I have following questions, in case my L1A COS decision was not approved by Dec15th.

Can I stay in USA till the decision comes out, post I-94 expiry?Can I continue to work for my employer in USA till the decision comes out, post I-94 expiry?Please suggest. Thanks in advance.
