" All American citizens, whether born here or elsewhere, whether of one creed or another, stand on the same footing; we welcome every honest immigrant no matter from what country he comes, provided only that he leaves off his former nationality, and remains neither Celt nor Saxon, neither Frenchman nor German, but becomes an American, desirous of fulfilling in good faith the duties of American citizenship. "
