Location voiture Porto Rico

Je serai en voyage à Porto Rico et je veux me louer une voiture.  J'aimerais savoir s'il vous avait vraiment fallu le permis international?   Car la politique de l'état dit:   ~This policy states: “A valid driver's license from the customer's country of residence is required and must be presented at time of rental. The driver's license must be valid for the entire rental period. Temporary licenses are not accepted. If the driver's license is in a language other than English, an International Driver's Permit/License is required in conjunction with the country of residence driver's license.  Qu'en est-il donc exactement?  Merci!
