I'm considering flying to New York, spending a week and then continuing to Montreal by Train before flying home to Europe.
I've been trying to find out whether Amtrak (the US train operator) records passport info to the CBP (US border agency) so they can establish my departure (airlines do this), without getting any useful answer.
However, I also know, having read it on the CBP Website, that paper I-94W forms (the ones you get when entering by land) can be handed in to CBSA (Canadian border agency) officials, who will pass on the data to the CBP.
My question is: can I similarly hand in a printout of the electronic I94 record (what you receive when entering the US by air) to CBSA officials, or do they only "accept" the old paper version?
If all else Fails, the last Resort is sending my Train ticket, passport copy with Canadian entry stamp, and electronic I94 printout along with an explanation letter to a dedicated address in Ohio. However, I'd really prefer it if there's any other means, either Amtrak passing on my data to the CBP, or the CBSA taking my electronic I94 printout and passing it on.
