It is not mandatory to travel to Luxembourg if are you a finalist.
A ceremony to announce the winner will take place at the museum on the opening night of the group exhibition of artist-finalists.
We understand that it may not be possible for you to travel at that time of year or for other reasons. It is not at all a problem if you cannot attend. In any event, whether you are present or not, you have the same chances as any other finalist of being chosen as the winner by the jury.
If you are absent, the director of the museum will serve as your representative and the museum will send you your finalist's certificate by Fedex after the ceremony. If you are the winner of the prize this year, you will receive the winner's stipend directly in your bank account just as if you had been present in Luxembourg.
