What the State Department (probably, I don't work for them) means is that naturalizing as a United States citizen may be done with no input from a person's other country of citizenship. Contrast with, for example, Germany, wherein a naturalization certificate may not be delivered to an applicant before the applicant shows that he or she affirmatively renounced any other citizenships or received permission from the German government to proceed with naturalization absent that step being taken.
