Hi. I obtained French citizenship not too long ago, and with it, I changed my name to something a little more French. Basically, there's just a mention on my French birth certificate that "[old name] is allowed to legally call himself by [new name]".
It doesn't say anything about my old name being changed, just that I'm legally permitted to use this new name. I assume that's because France has no jurisdiction over the names of citizens of other countries. So, basically, what I'd like to confirm is if I can still use my British identity? As far as Britain is concerned, I'm still my old British self, correct? Unless I choose to change my name on my passport I suppose, but I don't. I like my British name and wish to keep it if possible.
Thanks for reading.
