California being one of the largest economies in the world and a major port of entry for the entire country/continent if you excluded the foreign professionals you would deplete the pool by roughly 60%. If you knocked out non resident dual resident-Californian's well it would be over 80%. Sacramento is the state government capital and medical mecca for the world in several fields to mention only a couple of reasons.

Since USA citizenship is so highly prized you would be amazed at the number of foreign nationals that seek dual citizenship or American citizenship. Sometimes at major expense and effort.
