Maintain Valid Status

Hi, I received “Maintain Valid Status” as RFE after filing amendment. Uscis is requesting to share payslips from March 2017 to till date. But my H1 was approved only Feb 2021.
My history is I was on L1B from May 2014-Jan 2018. Not continuously. On and Off.
My extension got denied and I left India. Entered back to USA on Jan 2018 with H4 Visa. How to prove that I maintained valid status and didn’t stayed illegally.
Thanks.

You have to send the L1 pay slips for whatever time you were in the US. If you were on H4 visa, then you have to show the proof of H4 status with H4 i94 and H4 visa stamp.
