Travel Agent In Kashmir

A visa is an indication that a person is authorized to enter the country which "issued" the visa, subject to permission of an immigration official at the time of actual entry.
The visa fees charged are at the discretion of each embassy.

Some Types of visa:
transit visa, tourist visa, business visa, temporary worker visa, on-arrival visa, student visa.
Visas can also be single-entry which means the visa is canceled as soon as the holder leaves the country; double-entry, or multiple-entry which permits double or multiple entries into the country with the same visa.
Many countries have a mechanism to allow the holder of a visa to apply to extend a visa. For example, in Denmark a visa holder can apply to the Danish Immigration Service for a Residence Permit after they have arrived in the country. In the United Kingdom applications can be made to the UK Border Agency.
Common visas:- the Schengen Visa may be the best-known example of a common visa. This visa has it origins in the 1985 Schengen Agreement among European states which allows for a common policy on the temporary entry of persons (including visas). The visa allows a tourist or visitor access to the area covered by the agreement (known as the “Schengen Area” or “Schengenland”).
Exit visas :- Some countries have a requirement that an individual obtain an exit visa (ie. permit) to leave the country. This happens mostly in countries where there is political, economic or social turmoil that results in an increased rise in emigration. Sometimes this requirement also applies to foreign nationals.
Saudi Arabia and Qatar have an exit visa requirement, particularly for foreign workers.
