Visitor Visa Canada SSSS Immigrations, the Best Immigration Consultant Calgary, offers Temporary Resident Visa (TRV) to Canada for those who wish to visit study or work in Canada. The main purpose of a Canadian Visitor Visa, by Immigrant Services Calgary, is for short and temporary stays in Canada. Some countries have an existing agreement with Canada and are therefore exempt from this requirement. The main reason people contact us about visitor visas are that they have been previously refused. A Visitor Visa or Temporary Resident Visa (TRV) also, is an official document issued by a Canadian visa office that shows that you have met the requirements for admission to Canada as a temporary resident (either as a visitor, a student, or a worker). TRV being an official document issued by a Canadian Immigration Visa Office outside Canada shows that the holder has satisfied the requirements for admission to Canada as a visitor. TRV's can be for single entry or multiple entries. As a general rule, tourists are admitted for a period of six months. Temporary foreign workers and international students are admitted for varying periods of time, as determined on a caseby-case basis. Extensions may be applied for from within Canada.
