Arianna was the keynote speaker for a Naturalization Ceremony this Friday at Colonial Williamsburg.
She praised the "truly incredible array of countries represented here ... that for me is the strength of America."
"You overcame a lot of obstacles," Arianna said to the candidates. "I'm sure many of you moved mountains to be here. Please keep the spirit alive, because there are many mountains that still have to be moved."
According to The Virginia Gazette, 100 candidates from 48 nations participated in the ceremony to become American citizens.
