Saudi Arabia hosts millions of workers from South Asia and Africa, who contribute significantly to its economy. However, the country lacks a formal immigration system for non-Gulf Cooperation Council citizens to gain permanent residency. The Kafala system, which governs immigrant labor rights, has been criticized for exploitation and human rights abuses. The country is relatively less open to refugees, with exceptions made for Yemeni and Syrian nationals under specific conditions.
