UAE:

Citizens of the United Kingdom, the old 15 EU countries, Switzerland, Norway, Vatican City, Iceland, Andorra, San Marino, Liechtenstein, USA, Canada, Australia, New Zealand, Japan, Brunei, Singapore, Malaysia, South Korea and holders of Hong Kong SAR passports will be granted a free of charge for One Entry Visit visa on arrival in the UAE.

The visa enables them to stay for 60 days

The visa is renewable for a total stay of 90 days for a fee of Dhs 500.

Dubai Naturalisation and Residency Department (DNRD) :- Could help with visa sponsorship questions, especially involving spouses etc. [3]

Small Business Group Info:
Small Business Incubator: They meet every 3 months - this is the women's business site but the Incubator group is for everybody. - [4]

And another business group that meet regulary: [5]

The British Business Group site: They have sub-groups and one is for 'entrepreneurs' so anyone with their own business can join. - [6]

The UAE Labour visa ban: Regarding the 6 month visa ban if you leave a job - [7]

Quote: Highlight: Lt Col Al Khidhar said foreign workers leaving their jobs will no longer have an entry ban stamped on their passports, enabling them to re-enter the country on any type of visa, other than employment.

So not much good if you're looking for a new job or got one in the works, will still be banned from working for six months....but it's something I guess...

[edit] Setting Up a Business

Setting up a business here can be a real pain . It can be done but it will take a bit of time and more paperwork than you would believe. Yes there are dedicated areas for certain industries and different licence types, you will also need a local partner if you set up outside a free zone.

Also if you want to employ anyone, then you need to sponsor their residency,which entails deposits etc to the government, also if you are paying market rate for cheap labour then you would also have to supply housing, so bear that in mind when calculating costs.
