Hi, I have my current I797 approved till May 2nd 2021 with same H1 stamping date. I got my new H1 approved from 5/03/2021 until 4/1/2024 with the same i94 dates. Can i travel to india during Feb and come back with my existing old visa ? I am not planning for stamping. Will my i94 issued based on new approved petition (Till 2024) ? Also if i receive I94 until May 2nd at POE will the extension I94 in future override the POE I94.
