I was accepted to a Masters Program at EPFL 5 days ago. I am currently collecting all the necessary documentation to apply for a visa. However there is a chance it will take longer than I have to get to Switzerland (have to be there by September 30). My only idea right now is to use my passport to get to Switzerland as a tourist. Remain there until I get the visa (the 90 days are enough to guarantee that if I get approved I get the visa on time), cross the border to France, cross the border back again with the student visa.
Has anyone done something like this? Is this even legal? I tried contacting EPFL and the Swiss consulate and they were not helpful.
Additionally, EPFL wants me to sign a web form confirming or denying my attendance to the Masters program by June 30 (this weekend). They gave me essentially a week and a half to make the entire decision. Do I have any real obligation to stick to my word? If I say I want to go but it turns out I win the lottery or get into a different program afterwards I prefer and no longer feel like going to Switzerland will something happen? I.e what happens if I go back on my word (EPFL also was very unhelpful answering this question).
