Need to Understand Actual Work Authorization Date on L1 Visa

Hi There,

I have 3 different date on my L1 Visa, I-129s, I-797 and I-94 documents.

My Visa expiration date is on month of March 2020, my I-129s expiration date is on month of March 2019, I-797 Expiry date is September 2018 and 1-94 expiry date is March 2020.

Also in My Visa PED (Petition Expiry date) is mentioned as September 2017

Can you please help me understand what exactly these dates’ means to me and till what date I am authorize to work in USA?

Really appreciate you Comment and feedback.

Thanks in Advance.

You can work until your I-94 expires, so Mar 2020 in your case.
