Davila, 20, signed a five-year contract at the weekend but will spend the season in the Dutch Eredivisie to gain experience of European football.
"He is an open guy who will fit perfectly into our group," Vitesse technical director Ted van Leeuwen told the team's official website. "Ulises is very motivated to come to Vitesse Arnhem."
Mexico Under-20 international Davila received a call-up to the senior national squad this summer but is yet to make an appearance. He scored three goals to help the Under-20s finish third in the World Cup earlier this year.
