Yes. Those documents are required. You can use the tools on this page: atlasvisa.co/country/france to get those for free. Which country’s Schengen visa are you applying for? And is this short-term or long-term?
I have planning to apply Schengen visa and I have collected all the documents along with Flight Itinerary, Hotel Confirmation from http://www.schengenvisaitinerary.com but my question is it necessary take those documents some people saying not necessary. Please give me some clarification about this.
