I don't know if you actually need a visa if your wife is a French citizen. Does she have a French passport? You should contact the government first before you arrive to be sure. You can always extend tourist visas, but can't change to a work visa without leaving the country again. It is very difficult to work in French Polynesia because they want locals to work first. If you already have an offer of employment, it may be OK, but you should contact the government group Service de lEmploi de la Formation et de lInsertion professionnelles to get the facts. Their number is 689-46-12-12. Have your wife talk to them, if you don't speak French. Hope this helps.
