"Do Canadian citizens need a visa and/or a Machine Readable Passport to enter or transit the United States as part of the Visa Waiver Program?

A: As of October 26, 2004, the U.S. Visa Waiver Program requires visitors from various countries to have Machine Readable Passports to enter the U.S. This requirement does not apply to Canadian citizens even if the passport is issued abroad. Canadian citizens generally do not require a visa to travel to the United States. However, non-citizen permanent residents of Canada (and their children) as well as a list of other people (i.e. foreign government officials, officials and employees of international organizations, treaty traders and investors, fiancé/es and children of fiancé/es) do require a non-immigrant visa to enter the United States. Additional information is available from Passport Canada. The U.S. Customs & Border Protection agency of the U.S. Department of Homeland Security also provides information.

Please consult the update on the status of the Western Hemisphere Travel Initiative for information on the proposed requirement for passport or alternate secure document (still to be determined) for entry of all visitors, including Americans and Canadians, to the United States."

To be secure, and to verify that she is allowed re-get admission to, i'd provide the border provider a decision and double verify the fashion of files she will be able to favor.
