A visa is a conditional authorization granted by a territory to a foreigner, allowing them to enter, remain within, or to leave that territory. A visa is subject to entry permission by an immigration official at the time of actual entry, and can be revoked at any time. The modern visa may be a sticker or a stamp in the passport, or may take the form of a separate document or an electronic record.
About Travel visa in brief
A visa is a conditional authorization granted by a territory to a foreigner, allowing them to enter, remain within, or to leave that territory. A visa is subject to entry permission by an immigration official at the time of actual entry, and can be revoked at any time. Visas are associated with the request for permission to enter a territory and thus are, in most countries, distinct from actual formal permission for an alien to enter and remain in the country. The modern visa may be a sticker or a stamp in the passport, or may take the form of a separate document or an electronic record of the authorization, which the applicant can print before leaving home and produce on entry to the visited territory. Some countries require that their citizens, as well as foreign travellers, obtain an ‘exit visa’ to be allowed to leave theCountry. The World Tourism Organization announced that the number of tourists requiring a visa before travelling was at its lowest level ever in 2015. The need or absence of need of a visa generally depends on the citizenship of the applicant, the intended duration of the stay, and the activities that the applicant may wish to undertake in the countries he visits. The exact conditions depend on the country and category of visa, but some countries require a medical test that includes an HIV test, even for short-term tourism. In Russia and Uzbekistan, however, the HIV test is sometimes not strictly enforced. In the late 19th century and early 20th century, passports and visas were not generally necessary for moving from one country to another.
The relatively high speed and large movements of people travelling by train would have caused bottlenecks if regular passport controls had been used. Passports and visas became usually necessary as travel documents only after World War I. Some countries—such as those in the Schengen Area—have agreements with other countries allowing each other’s citizens to travel between them without visas. Uniquely, the Norwegian special territory of Svalbard is an entirely visa-free zone under the terms of the SValbard Treaty. In the modern world, visas have become separate secondary travel documents, with passports acting as the primary travel documents. Some visas can be granted on arrival or by prior application at the country’s embassy or consulate, or through a private visa service specialist who is specialized in the issuance of international travel documents,. These agencies are authorized by the foreign authority, embassy, or consulate to represent international travellers who are unable or unwilling to travel to the embassy and apply in person. The issuing authority, usually a branch of the country’s foreign ministry or department, and typically consular affairs officers, may request appropriate documentation from the applicant. This may include proof that the person hosting the applicant is able to support himself in the host country, proof that he or her really exists and has sufficient room for room for his or her home, etc. Other countries ask for proof of health status, especially for some persons with certain illnesses, such as AIDS.
