While Dubai tries to promote itself as the business and entertainment capital of the world, the government has a complex and at times frustrating work permit procedure that one should not attempt on their own unless they have prior experience. Therefore, it is best to go through official channels when looking for work in Dubai as spot inspections are frequent and if found working illegally, both the employee and the employer will be subject to fines and even deportation.
All the necessary forms and documents are written and processed in Arabic and is best left to a professional or a "P.R.O" to handle your paperwork.
Different nationalities have different rules about changing jobs and its frequency. South Asian Nationals have to work for a minimum of 1 year before looking out for another opening elsewhere or face a 6 month ban on working in the country. Western European and North American nationals however, need not worry as this rule does not apply to them.
With the price of rentals ever soaring in Dubai and neighbouring Emirates, it is a good idea to discuss a housing allowance when negotiating a pay package.
Despite all this, there are a few upsides, Dubai companies are generous with holidays averaging almost 39 days a year of paid vacation (including public holidays), a round trip ticket home once a year (depending on your contract) and most importantly all your earnings are 100% tax free!
Recruitment fraud is quite pervasive in this part of the world. Read your employment contract carefully before signing and do not pay any fees to recruitment agencies, as they are usually paid by the companies. Your passport is your personal property and cannot be withheld by the employer unless you are in a position of trust or are handling large sums of money.
