At the time of filing, applicants generally must hold an unlimited/permanent or unrestricted right of residence (e.g., B/C/D, E+, F+ or equivalent). Evidence usually includes language knowledge (national language) plus integration/economic participation depending on the declaration case. File is submitted at the commune civil registry.

Dual citizenship: Allowed
