TLDR: Can my children have 3 citizenships/passports?
In my mind I believe the idea of dual-citizenship, is an "agreement" between 2 countries, however this does not limit you from only having 2 citizenships.
I know that some countries you need to "ask" for and be granted permission before taking up another citizen (i.e. South Africa has this rule). I also believe minor's do not have to ask permission?
Anyhow, my children have South African & Italian (as I hold these), however we're in a position to apply for British citizenship too (we're more interested now due to brexit, previously not worried at all because of the EU treaty).
We've done the 5 years & have settled status, it's just a matter of applying at this point. We just want to understand the legalities/complexity around it.
P.s. Bonus points if someone can clear up the process for Adults too
