I am Filipino citizen and I have a National Visa (Type D) valid but I want to go to Istanbul, Turkey first with an e-Visa. Philippine Passport holders can visit Turkey for 30 days with an e-Visa as long as they have an active Schengen visa/Residence permit.
The problem is, I have a scholarship and I need to show proof (plane tickets) that I departed from my home country and landed in the Schengen area. I might get into trouble with my scholarship if they see that I went to Turkey first - it's too complicated to explain this to them because I'm basically just going to be a tourist there.
My other reason of going to Amsterdam first and then flying to Turkey is because it is cheaper. It will only cost me $700 and if I go straight to Istanbul and then to Amsterdam it'll be almost $900.
Is there some kind of a rule/minimum days of stay in the Schengen area for an individual before he/she can leave the Schengen, whatsoever?
I have a multiple entry visa. I just don't want to get into trouble for only spending one day in the EU and then going to Turkey for two weeks and then coming back again.
Will that be somewhat problematic?
