Canada's Supervisa Program
Canada has given out more than nine million 10-year visitor visas since the program began, with by far the largest bulk of recipients coming from China and India, followed by people from Brazil and Mexico.
The super-popular multiple-entry visas are generally a benefit to Canada’s economy, say immigration lawyers. But they caution the 10-year, multiple-entry visas can be abused by “shadow investors” to avoid paying property and income taxes in Canada — and as a dubious means by which to claim asylum.
