Canada to United States visa requirements

Canadian citizens enter visa-free for ordinary tourism or business visits and do not need ESTA. Canadian ordinary passport holders generally travel to the United States for tourism, visits, transit, or temporary business without a nonimmigrant visa and without ESTA. Present a valid Canadian passport when flying; at land and sea borders, CBP also lists WHTI documents such as a NEXUS, SENTRI, or FAST trusted-traveler card, or an Enhanced Driver's License/Enhanced Identification Card where issued. CBP officers at the port of entry decide whether to admit the traveler and set the authorized stay; B-2 visitor admissions with an I-94 are generally for six months unless an exception applies, so travelers should check any passport stamp or electronic I-94/admit-until date rather than assuming a full six months. Paid work, study for credit, immigrating, treaty-investor/trader travel, fiance(e) travel, and other listed special categories require the appropriate U.S. status or visa. Canadian permanent residents who are not Canadian citizens are not covered by the Canadian-citizen exemption and must use ESTA if eligible by nationality or obtain the required visa.
