To work in the UAE you must have a sponsor. This can be someone already living there or an employer who will sponsor you for admittance so you can take up a job.
There are different kinds of Dubai visas for Nigeria citizens for different kinds of work and lengths of stay and the one you need will be decided on the basis of a number of things that are taken into account like whether you are coming to work or for a holiday, the country you are coming from.
If you are already a citizen of one of the countries in the Gulf Cooperative Council then you don't actually need a visa - merely your passport (those countries are Kuwait, Bahrain, Saudi Arabia, Qatar, The United Arab Emirates, and Oman).
Otherwise, you will receive your visa on arrival at the airport.
If you are a citizen of an Arab Gulf Country Council (but not one of the GCC countries) and belong to a list of certain professional occupations then you will be allowed a 30-day visa. These occupations tend to be the professions - of doctors, accountants, engineers, and public sector workers.
If you belong to one of the countries on an approved list then you can get a free single-visit visa - but verify with a UAE embassy before traveling. The countries on the approved include the UK, USA, Canada, New Zealand, Japan, the countries within the EU, and some others. A full, up-to-date list can be seen on the UAE immigration services website.
If you don't qualify for an online Dubai visa for Nigeria passport holders under any of these more-or-less automatic criteria, then you must apply for a visa through a sponsor. The sponsor must sort out all of the paperwork on your behalf:
A sponsor in the Hotel and Tourist Industry can apply for a 14-day Service Visa, a 30-day Tourist Visa, or a 30-day Visit Visa which can be extended for another 30 days later.
Airlines can apply for a 4-day Transit Visa for airline staff.
Other sectors within the UAE can only seek to obtain Visit visas and Service Visas but not Tourist Visas.
If you have a friend on relative already living in the UAE then they can apply for a visa on your behalf as a sponsor.
