In 1952 Congress passed a joint resolution declaring Sept. 17 as a day of commemoration for the signing of the U.S. Constitution and "National Citizenship Day" to recognize all those who had attained American citizenship. In 2005 it was formally named "Constitution Day and Citizenship Day" in Public Law 108-447, the Consolidated Appropriations Act.
For more about the creation of this commemorative day see the Law Library of Congress' page, "Constitution Day and Citizenship Day."
