Hi,
I am planning to apply for PhD at FMI, Switzerland. I f I were short listed for the interview is there any possibilty for FMI to sponsor my travel expenses?

I think you would have to ask FMI! They may well pay for your travel expenses for an interview or they may wish to interview you by telephone instead. Good luck.

If you receive an invitation to interview, then is the time to ask. They won't be offended.
