Referring to the laws of the naturalization act of 1790 which forbade black and native (nonwhite) citizenship.
Did anyone from the ottoman lands challenge this statute to be considered white? If they weren't when would this have changed?
Further question: would it matter if I am Muslim or Christian?

Looks like there are a few examples of this. And at least one confirmed us citizen from the ottoman empire, who naturalized in 1880. Hajji Ali.
