Alexander Hamilton (an immigrant):
"To admit foreigners indiscriminately to the rights of citizens, the moment they put foot in our country … would be nothing less, than to admit the Grecian Horse into the Citadel of our Liberty and Sovereignty. … The United States have already felt the evils of incorporating a large number of foreigners into their national mass. … In times of great public danger there is always a numerous body of men, of whom there may be just grounds of distrust; the suspicion alone weakens the strength of the nation, but their force may be actually employed in assisting an invader."
