I have my initial petition picked up in lottery in 2016. But my company send me for stamping in 2017. Since the initial petition was for 2016-2019, my H1B visa was granted for 2017-2019. Now before I land up in US, my company filed amendment and I received new I-797B valid for 2018-2021. I landed in US in 2018.
My question is, I have my visa stamped till 2019, so do I need to return to my home country and apply for extension till 2021? Need to understand what are the process in this case.
Any help is much appreciated!!
