I got a long-stay visa for France valid for one year (03-12-2018 t0 03-12-2019). After 7 months, I got my carte de séjour (01-07-2019) valid for 4 years.
Last week I lost my wallet and my carte de séjour. I extracted a lost declaration from the police station, and I am waiting for an appointment to go to the prefecture to obtain a duplicate one, but I heard that it might take more than 3 months to get the duplicate one. I have a planned trip for 3 days in November outside France.
Can I travel using this visa, or after I got the carte de séjour, the visa is not valid anymore?
