Hey Jackson,
Thanks for the help.
Do you know if it is necessary to present a return ticket upon arrival as a tourist?
It seems like entering as a tourist first and waiting for the WHV is the best way to organize my trip right now. But I don't want to risk any problems...
It shouldn't be an issue for France customs, but normally during flight check-in the airline will ask to see a return ticket, though it's not a universal rule. If you explain that you have a long-stay visa starting soon, they should understand. The airline might also ask you why you're flying before the start of your visa so you need to be prepared to answer that.
