Beneficiaries of protection are entirely free to settle in any part of the French territory. They are not restricted to specific areas.
The law states that the duration of validity of travel documents is defined by Article 953 of the General Tax Code: 5 years for refugees, if it is a biometric travel document, and one year for beneficiaries of subsidiary protection.[1] French law does not provide for duration of validity of non-biometric travel documents. Official French websites, however, assert that the duration of validity of travel documents for refugees is 2 years.[2] In practice, whereas the law is clear on the 5-year duration, Prefectures issue only 2-year travel documents for refugees.
