I have got Schengen visa -spain and due to travel June first week . This is a single entry business visa and I am traveling to Madrid for business meetings.After the visa is secured I was thinking of flying to Paris from Madrid and spend two days there before returning from Paris CDG to Muscat Oman ( visa issued by Spanish embassy muscat )Does it cause any problem traveling to Paris with as I have not mentioned in visa application to spain embassy of my travel plan to Paris? I am concerned if there could be trouble in Madrid airport immigration on arrival as my return ticket is from Paris not from Madrid as visa application was for business not tourist purpose.Visa valid for Estados Schengen , visa type : C single entry , duration of stay :15 days , remarks : VIS Estancia. Under remarks it is written indomeest.I have travelled to spain and Germany earlier but have not changed my travel plans after getting visa to travel to another Schengen state. Please advise.
