Some of the most recognizable brands and service providers worldwide are on this list. Who knows if Apple would be in existence today bc Jobs and Wozniak were both children of immigrants. In Jobs case, his bio father was a Syrian. Do you really think Jobs would have the same access to tech, resources and the Woz to cofound Apple?
Or, Jeff Bezos of Amazon... great-grandchild to Irish, Swedish and Danish immigrants (and, strangely enough, cousin to George Strait). Moral of the story, immigrants made America great because we invested in all of our people legal immigration status or otherwise.
