An investor visa in Dubai allows foreigners to live and work by investing in real estate (min. AED 750,000 for a 2-year renewable visa) or a business, offering long-term residency, family sponsorship, and full business ownership options. Key types include the 2-year property visa and the newer Green Visa for business/entrepreneurs, with longer durations (5, 10 years) available for significant investments, all facilitating access to Dubai’s business ecosystem.
