Italian immigration law requires every person entering Italy (who is not resident in a country in the European community) to apply for a “permesso di soggiorno” within 8 days of arrival.
To do this you have to present yourself at the local police station with your passport and inform them of where you are staying and how long you will be there. This procedure is a formality and most people (holiday makers and business men on short trips) don’t bother and no one seems to mind. Unfortunately with WWOOF and the situation of voluntary “work”, not having the permesso di soggiorno could create problems so please for your own peace of mind discus this with your host and make the effort to get one.
Please note. We cannot help with visa applications or write invitation letters.
