Recently travelled to the US this past January and discovered the I-94 / I-94w arrival/departure forms are no longer needed. CBP now gathers travelers’ arrival/departure information automatically from their electronic travel records. I've got a bulk of these forms which I would pre-fill prior to my trip that will now make great starter material for the fireplace.
