MOVING TO FRANCE ?

If you settled in France after the 1 January 2021, you must apply for a residence permit for non-European nationals at your local prefecture.

British nationals settled in France after 1 January 2021 are subject to the provisions of the common law, except when they are members of the family of a British national settled in France before that date.

All British nationals and family members over 18 who wish to settle in France for a stay of more than three months must hold a residence permit.

Minors under 18 years of age are exempt from this obligation unless they need a residence permit to work.

A residence permit must be issued directly in the prefecture.
