I have obtained my visa to study in the Schengen area. It is valid from September 4. However my flight is on September 2 (flights are full and I cannot change it). I can enter the Schengen area as a tourist on my second passport and then once my visa is valid I can remain and study in that area legally with my other passport.
Will it be an issue if I do not have an exit stamp on the passport I have entered? Will it be an issue if I do not have an entering stamp on the passport that carries my student visa? How can I approach this issue without having to fly out of the Schengen area with the passport I have entered and reenter with my valid visa?
I plan to study in Spain.
