I am answering this question considering that you want to apply for Schengen visa for tourist purposes.Well, I’ve always thought of writing a post about this as I spent quite some time researching on this topic, but never really made it. But thank you for the question, I’ve got a chance to help folks out.As an Indian in the US, one of the most important things is to have a proper itinerary with you. So let’s say you have a Europe trip planned, you need to identify which is the country where you will have the maximum stay, that’s the consulate where you need to apply for the Schengen visa. For example: If your trip comprises 3 days in Germany, 2 days in Italy, 1 day in France, then you need to apply at the German Consulate.
