Does it matter during immigration (in India while leaving for the US or at the US CBP) if an expired US stamp is faded or marked while the valid visa is in pristine condition in the Passport. The old visa expired in 2018 which is fading a bit and has a pen mark, but the new visa valid till 2021 is in pristine condition.
Nobody at the US border is going to care much about your old and expired visa. After all it is old and expired. US CBP is only going to look at your current visa, and the same for the airline.
India probably isn't even going to care unless you have an ECR passport, but again only your current visa is of any importance, and it's not for a GCC country anyway.
