I am a Russian citizen living in Canada and there are two scientific events in Europe in which I would like to participate this June: one in Greece, one in France. There are about 10 days in-between them. I would also like to stay as a tourist in-between these events but this is optional.
Should I apply for two separate Schengen visas? If I apply for two visas, will both embassies need to take my passport at the same time? In which application should I mention tourism?
Or is it possible to apply for only one visa and provide supporting documents for both events? Which country should apply to in this case?
