1. Single Entry: Single Entry Visa allows only one-time entry for a certain period.
2. Multiple Entry: Multiple entry visa allows you to enter and exit as many times as you want in a given time frame.
3. Super Visa: Super Visa is for parents and grandparents of permanent residents and Canadian citizens.
The significant difference between a multiple entry visa and a super visa is that the super visa allows an individual to stay up to 2 years at a time. In contrast, with a multiple entry visa, one can only stay for up to six months at a time.
