A tourist visa is a provisional permission granted by a nation to a foreigner, permitting them to enter and temporarily stay within, or to leave that country. Such visas typically include limits on the duration of the foreigner’s stay, territory within the country from the time they may enter, the dates they may enter, the number of permitted visits or an individual’s right to work in the country. Visas are linked with the application for permission to penetrate into a country and thus are, in some nations, different from real formal permission for a non-resident to enter and remain in the country. In each instance, a visa is subject to entry permission by an immigration official at the time of actual entry and can be abrogated at any time.
