Dubai: Dubai sits at the crossroads of hundreds of destinations, making it a popular stopover for travellers passing through Dubai's airports.

The transit visa is a single-entry visa, valid for entry within 30 days of its issuance, and is not extendable.According to UAE’s laws, you can select from one of two durations for transit visas – either 48 hours or 96 hours from the moment your visa is stamped at the immigration counter at the airport.Do I need to apply for a transit visa?Musa Dayani, a Dubai-based public relations officer, confirmed that travellers need to apply for a transit visa in advance if they are not GCC citizens, and if they are not eligible for visa-free entry or visa on arrival in the UAE.
