Visa Assistance in mumbai
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.
A visa generally gives non-citizens clearance to enter a country and to remain there within specified constraints, such as a time frame for entry, a limit on the time spent in the country, and a prohibition against employment. Some countries do not require a visa in some situations, such as a result of reciprocal treaty arrangements. The possession of a visa is not in itself a guarantee of entry into the country that issued it, and a visa can be revoked at any time.
A visa application in advance of arrival gives the country a chance to consider the applicant's circumstance, such as financial security, reason for applying, and details of previous visits to the country. A visitor may also be required to undergo and pass security and/or health checks upon arrival at the border.
