No fellow-citizen of ours is entitled to any peculiar regard because of the way in which he worships his Maker, or because of the birthplace of himself or his parents, nor should he be in any way discriminated against therefor. Each must stand on his worth as a man and each is entitled to be judged solely thereby.
There is no danger of having too many immigrants of the right kind.
 Theodore Roosevelt, State of the Union Address. copy citation

Context

“In the field of statesmanship, in the field of business, in the field of philanthropic endeavor, it is equally true that among the men of whom we are most proud as Americans no distinction whatever can be drawn between those who themselves or whose parents came over in sailing ship or steamer from across the water and those whose ancestors stepped ashore into the wooded wilderness at Plymouth or at the mouth of the Hudson, the Delaware, or the James nearly three centuries ago. No fellow-citizen of ours is entitled to any peculiar regard because of the way in which he worships his Maker, or because of the birthplace of himself or his parents, nor should he be in any way discriminated against therefor. Each must stand on his worth as a man and each is entitled to be judged solely thereby. There is no danger of having too many immigrants of the right kind. It makes no difference from what country they come. If they are sound in body and in mind, and, above all, if they are of good character, so that we can rest assured that their children and grandchildren will be worthy fellow-citizens of our children and grandchildren, then we should welcome them with cordial hospitality.” source
