With a foreign-born population representing more than a quarter of the state’s residents, California is a diverse and dynamic state. The proportion of naturalized and non-U.S citizens among the foreign-born population is about even. The high costs of naturalization for applications and fees, stringent requirements, added with the long time horizon to be granted citizenship deters new arrivals from becoming a U.S citizen. Therefore, we do not see a majority of foreign-born residents who are naturalized.
As for non-immigrant residents, those with I-94/Visitor visas only, their population in California has been rising rapidly since 2009. The relative weakness of the U.S dollar could partly explain this boost in non-immigrant arrivals. Two-thirds of the non-immigrant is tourists and those on business travel. Only four percent are temporary workers and families, and three percent are international students.
