So you did an extensive Google search and came up with a shill site run by visa agent scammers to quote? The authoritative Schengenvisainfo.com? Are you kidding me? Go apply for a Schengen visa from Italy from any Italian mission in the world and tell them that you are going to France first, at anytime after 2005 or so they will TURN YOU DOWN FLAT. Same for Spain, same for Spain and Germany. Now the big hole which I cited which can be an exception from time to time is if one flies into a big hub and then changes ones ticket, so the proverbial India with a Swedish Schengen visa shows a ticket BOM-FRA-STO and then decides to do a small layover in Germany, one might get away with that. But please do not start speaking about what Switzerland is/was, s noted above not only is it NOT an EU country, but before Schengen it borders were often "Swiss cheese" as anyone from anywhere in the World with a US Green card could enter the EU without a Schengen visa for decades, as the Franch passport control desk at GVA for example was unmanned for the better part of 20 years.
