Visitor Visas are issued to persons wishing to travel to a country for sightseeing or vacation. Tourist visas usually only authorize short stays (typically, up to a month, three months, or six months). Some countries’ visas (e. g. US, UK) may last as long as five or ten years (for periodic visits), but the issuance fee may be proportional to the length of visa. To successfully get this, you must demonstrate to the consul that you are definitely going to return home after your stay in their country. Employment is not allowed unless it is issued together or in conjunction with a working holiday visa.
A visa is a conditional authorization granted by a country to a foreigner, allowing them to enter and temporarily remain within, or to leave that country. Visas typically include limits on the duration of the foreigner’s stay, territory within the country they may enter, the dates they may enter, the number of permitted visits or an individual’s right to work in the country in question. Visas are associated with the request for permission to enter a country and thus are, in some countries, distinct from actual formal permission for an alien 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 revoked at any time.
A visa is most commonly a sticker endorsed in the applicant’s passport or other travel document. The visa, when required, was historically granted by an immigration official on a visitor’s arrival at the frontiers of a country, but increasingly today a traveller wishing to enter another country must apply in advance for a visa, sometimes in person at a consular office, by mail or over the internet. The actual visa may still be a sticker or a stamp in the passport or may take the form of a separate document or an electronic record of the authorisation, which the applicant can print before leaving home and produce on entry to the host country. Some countries do not require visas for short visits.
Some countries require that their citizens, as well as foreign travellers, obtain an “exit visa” to be allowed to leave the country.
