I am a researcher with an El Salvador passport (visa-free for 90 days to Schengen area) and I will be starting a PhD course of study in Austria. For this, I have received a visa-D but the consulate issued it with a validity date which is the same as my contract start date. I would like to arrive early to set up my apartment and acclimate to the 8 hour time difference before work and school start.
This shouldn't be a problem correct? The consulate here says that's how they issue D visas and I should be able to enter visa free but it makes me nervous. I have a plan which I'll show the border officer, which details what I'll do during my visa free stay, a return ticket to London (to exit schengen) and reentry on the start of my visa d validity. I did this to show them that I'd like the two "trips" to Austria to be totally separate from each other in purpose.
Your thoughts and expertise are appreciated!
