Does L1A Extension Rejection revokes approved I-140

[Tinsukia]

Dear Murthy Team,

I am currently on L1A Individual which is valid till Jan 2019 and my company has already started the extension process. Now, I have my I-140 approved and EAD valid till June 2019 and waiting for I-485 decision and have to wait until EB1 is current as my priority date is of November 2017.

I have one question and would appreciate if you can share some insights.

Q: If my L1A extension gets rejected, does it revoke my I-140?

Q: If answer to above is No, then I guess I can continue to work on EAD and can file my EAD extension until I-485 decision comes out.

Please let me know your thoughts.

Thanks
