Visas for Abu Dhabi
Most expats will be moving to Abu Dhabi under the auspices of an already established residency visa, either through employment sponsorship or family member sponsorship. Without this document, it's difficult to accomplish anything in the UAE.
Tourist visas for Abu Dhabi
Before you make plans to travel to the UAE, make sure you don't need to arrange a visit visa beforehand. Citizens of nations included in the GCC or of nations included in a list put together by the UAE do not need to organise a visa before arriving in the 
country; the UK, the USA, all Western European nations and Pacific Rim nations appear on this list, but India and Pakistan do not.
Those who do need a visit visa will need the sponsorship of a UAE resident or a UAE based company.
Formal, sponsored visit visas last 60 days, and in some cases, are renewable for a fee. Be sure to find out if you are eligible for a renewable visa if you're planning to stay longer than the allotted number of days. Visit visas are granted to those who are coming on holiday, family visits or long-term business.
Multi-entry tourist visa for Abu Dhabi
If you do business in the UAE frequently, it will be best to get a multi-entry visit visa. You must first obtain a standard, single-entry visit visa and then apply for the multi-entry visa once in the country. The multi-entry visit visa is valid for six months at a time, and each stay within that six month period can last up to 30 days.
Certain nationalities can apply for multi-entry visit visas that cover the course of a longer duration.
Residence Visas for Abu Dhabi
Expats who want to obtain a residence visa for Abu Dhabi will need to either be sponsored by an employer, which allows for the right to work and live in the UAE, or by a family member, which only allows for the right to live in the UAE.
