Visitor Visa
A visitor visa is an immigration document that permits foreign nationals to travel to and enter Canada is a visitor visa, also known as a Temporary Resident Visa (TRV). You will require a visitor visa to enter Canada, whether you are coming as a student, a temporary worker, or just to visit unless you are from a nation that does not require the visa.
There are mainly two types of visitor visas for Canada; single entry and multiple entry. Foreign nationals with a single entry visa can enter Canada only once. Holders of multiple entry visas can enter and leave Canada as often as they want until their visa is valid. There is no need to specify which type of application you want; all applications are automatically given consideration for multiple entry visas, with single entry visas only being granted in exceptional circumstances.
