The residency visa is arranged by the developer and is usually a 3-year renewable visa. It does not include a work visa. It is purely to allow the owner and his immediate family to reside here without needing to renew transit visas. You may be required to pay the fees depending on the developer. All visas are to be issued through the usual channels being the UAE Ministry of Interior – Department of Residency and Naturalisation. Please note that not all projects guarantee a residency visa, so check first if this is an important requirement.
