As so many recent posts have pointed out.
Hello, I am sorry to bother you. I was hoping you would have a better understanding of my situation regarding the process for Brits coming during the transition period?
Here is my situation:
I have got a rental agreement that starts in April. When I arrive, am I to visit my local prefecture or do I wait for the updated website.https://brexit.gouv.fr/sites/brexit/accueil/vous-etes-britannique.html
Will this updated website from the french government allow me to apply for a new carte Sejour without going to the prefecture? or is this just for people already resident in France?
I want to be legally resident before the end of the transition period, I just don’t know where to start. Any help will be greatly appreciated.
There is no need for you to ask questions in this thread, the thread that you started was the best place to ask and get answers.
Hi! Glad you found us. Welcome!
Please can you do me a favour and add your full real name to the relevant bit on your profile page 
Thanks!
