A Visa is a permit given by a country that allows an individual to go to that country. It names the kind of visit and says how long the person is authorized to stay. The Visa mentions the kind of Visa and the authorized duration of the individual’s stay. Sometimes, individuals are required to go through an interview conducted by the Embassy before they get a Visa. Many countries require Foreign Visitors to have a valid passport and a Visa before they can enter the country, but there are some exceptions. Visas are associated with the request for permission to enter (or exit) a country, but one needs to remember that it is not the same for all countries. Some countries require an actual formal permission for one to enter and remain in the country.
