Citizenship for kids of a British parent

[epi]

Hello,

I have a friend who is a naturalised British citizen, lives permanently in his home country and has 9 year old twins born there (outside the UK). Spouse is not British. Do I understand correctly that kids are automatically British and what is the right way to confirm their citizenship and get passports?

Thank you.

Provided the twins were born on or after the date on the naturalisation certificate, the children are British citizens by descent and can apply directly for a British passport. Depending on where they are located, it can take up to a year for them to get British passports.

Thank you! Means in their case there will be no proof such as a hard copy certificate confirming that they are British?

Correct. Because they acquired British citizenship at birth, there is no hard copy certificate confirming their British citizenship. Such a certificate (of either registration or naturalisation) would only be issued if they acquired British citizenship at some point after birth.

However, they will need to keep their father's naturalisation certificate and their own birth certificate safe as that that is the only proof of their (and their children's) British citizenship.

Of course, as British citizens by descent, their children will only be British citizens automatically if their children (your friend's grandchildren) are born in the UK. Any children born to the twins outside the UK will not be born British citizens.
