The United Arab Emirates authorities have taken many steps to make the immigration process as straightforward as possible. Apart from the fact that citizens of 39 countries (i.e. GCC nationals plus nationals of listed countries) do not require visas prior to arrival at a UAE airport, there are efficient systems in place to facilitate visitors not falling into one of the above categories. If you are coming to work in the UAE you will require a visa that can only be obtained on your behalf by your employer or sponsor.
All candidates will be issued with a visitors Visa in order to start work in the UAE. Upon completion of a probationary 3 month period, the candidate will then be given a residency permit. The residency visa is valid for 3 years once it is issued.
