There are over 40.7 million foreign-born residents living in America. Iceland, Bermuda, and Samoa have the lowest level of foreign-born population in the United States but it is Mexico that is head, shoulders, and torso above the rest with 28.2% of the foreign-born population from just aross the border. Russia, interestingly, is 20th (just ahead of Iran in 21st place). We can only hope not all Russian immigrants are currently HFT "traders."
