A single-entry visa permits entry to a country only once and is typically valid for a shorter duration, allowing a single entry and exit. If you plan to make multiple visits to the same country in rapid succession, it is advisable to apply for a multiple-entry visa. This type of visa enables entry to the country on more than one occasion. The approval of a multiple-entry visa is subject to the discretion of the issuing authority and may involve additional fees. The duration of visa validity is also determined at the discretion of the issuing authority. Therefore, it is crucial that your application form and supporting documents accurately reflect your intended travel dates.
