I recently submitted an application to the French Embassy for a tourist ('C') visa. In the application form for "previous Schengen visas issued during the last 3 years", I did not mention my 'D' visa - issued by Switzerland (it was issued a week before this French visa application).
This is because on the Swiss Embassy's website, it listed the 'Schengen' visa as a short-stay 'C' visa and the 'D' visas as long-stay. So I thought only the visit visas mattered. However after applying I realised, it could be 'Schengen' in that it is issued by a Schengen state etc.
So I would just like to seek your opinions on this.
N.B. I applied for a 'C' visa as well since my validity date for the 'D' visa does not start that soon and I need a visa to enter Europe.
