Ms.trisha, what's your nationality? As I know,
1. AGCC Citizens
Citizens of the Arab Gulf Co-operation Council (GCC) member states (Bahrain, Kuwait, Qatar, Oman, Saudi Arabia) do not need a visa.
2. AGCC Residents
AGCC expatriate residents may obtain a non-renewable 30-day visit visa upon arrival.
3. British Citizens
Residents of the UK, with the right to abide in the United Kingdom, may obtain a free visa on arrival, which is valid for 60 days and can be renewed for an additional 30 days for Dhs. 500 (US$ 137). Holders of the British Overseas Citizens Passport, who dont have the right to abide in the UK, will also obtain the free visa.
