United Kingdom - Passport & Nationality - British Citizenship by Birth (Settled parent)
A child can be registered as a British citizen where:
1) the child was born in the UK;
2) the child is still under 18; AND
3) neither of the parents were "Settled" at the time the child was born OR one of the parents subsequently becomes "Settled" after the child's birth.
If a parent was "settled" at the time that the child was born, then an application to register the child can be made at any time in the future. However, where the parent only became "settled" after the child was born, then the application must take place before the child turns 18. In either case, we always advise clients with children under the age of 18 to address their rights to British nationality before they turn 18. There are several routes to register a child as a British citizen, and these fall away away once a child turns 18 and can be lost forever.
The "Settled" status includes:
a) a British Citizen
b) an Irish Citizen
c) a person holding the UK Right of Abode;
d) a person hold Indefinite Leave to Remain; AND
e) an EU National holding a Permanent Residence Card.
