At several US land ports of entry, such as Blaine (coming from Vancouver by bus), although a paper I-94W form is always issued (pre-filled for those having an ESTA), officers are also able to generate an electronic I-94 (something I'd emphatically prefer for my own records, for example in case I were to lose the paper form somehow).
My question is: do the officers at the Vancouver Pacific Central station (where trains to Seattle depart from) have the facilities to do this as well?
