With decades of legal support and continuous services to foreign investors, Iran stands as one of the leading countries in the region in attracting and supporting foreign investment. This history is clearly evident with the enactment of the« Law on Attraction and Protection of Foreign Investments »(LAPFI) in 1955 (1334 in Iranian calendar) and the current law titled« Foreign Investment Promotion and Protection Act »(FIPPA) in 2002 (1381 in Iranian calendar).The array of facilities and privileges allocated to foreign investors in the legal system of the country, particularly the «Foreign Investment Promotion and Protection Act »and its Implementing Regulation, provide significant advantages such as the right to establish an Iranian company with 100% foreign ownership, ownership of immovable properties under the name of the established company in Iran, no restrictions on the amount and volume of investment, the ability to repatriate profits and proceeds from projects and the principle of foreign capital, granting five-year residency to investors, experts, and managers of the investing company, experts, and managers of the project company and their families. These facilities provide favorable conditions compared to other countries in the region for investors.
