I am an Indian national, currently living in the United States under a non-residence visa. I recently applied for and received a short-stay multiple-entry Schengen visa from the Italian consulate where I live and the visa explicitly states the visa type as "Turismo". I intended to use the visa to visit Milan as a tourist for a few days during Easter, with a short-stay in Geneva, Switzerland, for business purposes, and back to Milan for my flight back to the US.
However, due to several reasons, including the current security situation in Europe, I have had to shorten my stay in Milan. Therefore, I now want to land in Milan as originally intended, but instead of staying in Milan for tourism, I will be taking a train directly to Geneva for business and back to Milan a few days later for my flight back. I am thus essentially transiting via Italy.
Seeing as that the purpose of my visit has slightly changed, will this cause problems for me at Italian immigration?
Edit - I apologize for the confusion. My visa is of type 'multiple-entry'.
