International
Chiumiento was called up as a replacement for Johann Lonfat in Switzerland's UEFA Euro 2004 squad. However, he turned the call-up down as he still had hope of appearing for Italy. In February 2010, Chiumiento decided to play for Switzerland and made his first appearance for the Swiss national neam in a friendly match against Uruguay after having declined many call-ups. Although his dream was to play for Italy he decided he would play for Switzerland as he has a chance to be a regular in the starting team.
