If a Canadian does not have a Form I-94, does he not accrue unlawful presence until there is a finding that he violated the terms of his nonimmigrant alien status? Is the burden is on CBP to establish such a violation occurred?
U.S. Customs and Border Patrol (CBP) indicates that the mere fact that there is no I-94 does not determine whether or not an individual overstays. Moreover, an individual who is admitted as a B, but does not receive an I-94 either on the southern or northern border is in a legally materially different status than an individual who is admitted as duration of status. Canadians accrue unlawful presence irrespective of whether they have an I-94.
