US Customs and Border Protection has recently introduced a pamphlet, available on-line, that sets out information and instructions for the CBP Declaration Form (which every traveller entering the U.S must complete), Form I-94 (only applicable to some travellers, and not to Canadian citizens) and Form I-94W (used by visitors seeking entry under the Visa Waiver Program). Travellers to the United States may want to review the brochure in advance of travelling, especially if they are unfamiliar with these forms.
