H1B amendment reduced validity compared to i94 and extension petition

[Raakesh]

Hi ,

I applied extension and travelled to India in Aug-2017. I got extension approved in OCt2017 and company filed for amendment in Feb 2018 when I was in India.

I travelled with extension petition in June 2018.and my visa /i94 both have validity till AUg-2020.

I received amendment petition now  (I-797B) without i94 which has validity till Feb 2019. 

Please advise which date should i take . Do i need to file for extension again as the amendment valdidity is Feb 2019  or i94 valdity till 2020 is fine?
