I’m on an H1B visa since 2017. I extended in 2021 and again in 2023 (thanks to approved I-140). But my visa stamp in my passport is from 2017 which expired in 2020. I haven’t made efforts to get another stamp mainly because of the pandemic in 2020 and long appointment backlogs thereafter. Is there a necessity to always keep a valid visa stamp in my passport? Apart from the ease of travel are there any other reasons to always keep a current visa stamp in my passport? I do have all valid I-797 documents of status and have kept my status current all the time.
