Most first-generation migrants can naturalise after five years of legal residence, while French university graduates can do so after two. The CESEDA obliges spouses of French citizens to wait four years instead of three. The French-born children of migrants can become French by declaration when they turn 18, as long as they have lived in France or five of the past seven years. Their children are automatically French at birth. Migrants are eligible under provisions that rank second out of the 28 after CA and BE, but then go through conditions that rank 20th. Since the passage of the CESEDA, procedures cannot exceed 18 months. Authorities demand that migrants meet conditions such as language and integration tests and proof of good character. Applicants can receive a form that would gallicise their name by translating it to the French equivalent or by replacing it with a common French name. Migrants and their children born in the country are allowed to be dual nationals (see box).
