Most travelers need to obtain a visa prior to entering the emirate. However, the good news is that the UAE authorities have taken many steps to make this process as straightforward as possible. Citizens of 39 countries - GCC nationals plus nationals of listed countries - do not require visas prior to arrival at a UAE airport.
The kind of visa that you require for entry into the UAE depends on several different factors such as your nationality, the purpose of your planned visit and its planned duration.
