Visitor Visa is a temporary visa which is a conditional authorisation by the government granted to any foreigner (person not belonging to that particular country) to visit the country temporarily. A visitor visa grants the applicants permission to enter another country for a short temporary visit. The duration of the visitor visa may depend on the circumstances. It may be for 3 months or 6 months or more. Visitor visas are granted subject to fulfilling the requirements of the country you wish to visit.
