You need to pay the visa figure on the day of your interview and save the softcopy you get, since you would require it later, to present it to the consular officer as evidence for having paid the figure. The figure for a long-stay France work visa is around EUR 99. Still people who are exempted from paying the figure for work visa are the following:
- A family member of a citizen of the French
- A family member of an EU or an EEA or Swiss citizen
- A child espoused by a French citizen
