My sons (both under 18) hold French passports while I am British. In the years before Brexit they would spend a week each summer with their British grandparents in the UK, while their parents would return to France to work. Their grandparents would then bring them back home to France at the end of their stay in the UK.
Is this kind of arrangement possible in a post-Brexit world? Is there any special documentation that needs to be completed on either side of the channel in such a situation? Is a visa now required? Are we even able to 'abandon' our children in this way?
Getting them British passports is on my to-do list - would it make things easier?
