US Constitution, Article I (The Legislative Branch), Section VIII (Powers of Contress), Paragraph 4:

To establish an uniform Rule of Naturalization, and uniform Laws on the subject of Bankruptcies throughout the United States;

Note that it doesn't specify the broader category of "Citizenship", only "Naturalization". Congress only has the authority to pass legislation on Naturalization.
