Hi ashy and welcome to FT,

In theory, you are expected to get the Schengen visa from the country in which you will be spending the majority of your time. In my experience, if your plans should change it shouldn't matter too much. After all, the country through which you enter the Schengen Zone might be different from the one which granted you the Schengen visa for all sorts of reasons. As long as you can prove that you have an itinerary (hotel and travel bookings help tremendously) and that you have an onward ticket (i.e., that you are not going to overstay your visa and end up working illegally), you should be just fine.
