TRAVEL IN THE SCHENGEN AREA

You are reminded that holders of French residence permits (for example, the carte spéciale issued by the French Ministry of Foreign Affairs, a resident's card, a temporary residence card or a receipt issued during the renewal of such residence documents) do not need visas for tourist travel (including conferences) to countries applying the provisions of the Schengen Convention, provided that the duration of the travel is less than three months.
The countries applying the provisions of the Schengen Convention are Austria, Belgium, France, Germany, Greece, Italy, Luxembourg, the Netherlands, Portugal and Spain; and since 25 March 2001 Denmark, Finland, Iceland, Norway and Sweden.
For longer stays and for other than tourist visits, you are strongly advised to make enquiries at the relevant consulates.
