All nationalities other than citizens of Gulf Cooperation Council (GCC) countries need a visa to enter into Qatar. Since Qatar opened its doors to tourism, however, 31 different nationalities can now obtain a visa at Qatar’s airport, even though the regulations change in minor ways fairly frequently.
Citizens of the European Union, USA, Australia, New Zealand, Canada, Singapore, South Korea, Japan, Brunei and Hong Kong were eligible for a two-week, single-entry tourist visa, which is issued on arrival at the airport and costs QR100. Some visitors have reported having a three-week visa stamped in their passport upon requesting a two-week visa: there’s no harm in asking! To avoid being turned back from a lengthy queue, fill out the application card (in piles on top of the visa counter) before you reach the visa counter and have your credit card ready.
You must apply for a multi-entry tourist and business visa through a Qatari embassy or consulate. Three passport-sized photos are required and an application form filled out in triplicate. Anyone requesting a business visa needs to supply a letter from their host company. These visas are issued within 24 hours.
