I am under the Visa Waiver Program and when I entered the US by car I got a green paper form stapled to it, the I94W. This is the paper to turn in when I will leave the US that is the proof I leave the US.
But what if I lose my passport? I would lose the I94 along. If I get a new passport while staying in the US, in this new passport I will not have an I94. How do I do when I will leave, at the border or later? I am not flying out so using a plane ticket as a proof I left is not an option.
So, how to prove and signal I am leaving the US if I do not turn in the I94 because I lost my passport?
