On March 18th, thirty-nine people entered Mammoth Cave as immigrants and exited as United States citizens.
The park hosted the U.S. Citizenship and Immigration Services ceremony. Louisville Field Office Director Geoff Verderosa said that this was the first naturalization ceremony to be held in an NPS area in Kentucky and the first ever to be held inside a cave.
U.S. Magistrate E. Robert Goebel presided over the ceremony, swearing in the new citizens. Superintendent Patrick Reed congratulated the group and welcomed them to Mammoth Cave, one of nearly 400 NPS areas that belong to all citizens on the United States.
All arrangements for the ceremony were coordinated by the park's EO committee.
