Since the mid-1990s, there has been a steady stream of South African Jews, American Jews, and French Jews who have either made aliyah, or purchased property in Israel for potential future immigration. Over 2,000 French Jews moved to Israel each year between 2000 and 2004 due to anti-Semitism in France. The Bnei Menashe Jews from India, whose recent discovery and recognition by mainstream Judaism as descendants of the Ten Lost Tribes is subject to some controversy, slowly started their aliyah in the early 1990s and continue arriving in slow numbers. Organizations such as Nefesh B'Nefesh and Shavei Israel help with aliyah by supporting financial aid and guidance on a variety of topics such as finding work, learning Hebrew, and assimilation into Israeli culture.
