2. British citizenship
You can live and work in the UK free of any immigration controls if you’re a British citizen.
You might be able to apply to:
register as a British citizen - for example, if you have another type of British nationality
become a British citizen by ‘naturalisation’ - for example, after you settle in the UK
You might already be a British citizen based on where and when you were born, or your parents’ circumstances. Check if you’re a British citizen if you’re not sure.
If you were born in the UK or a British colony before 1 January 1983
You became a British citizen on 1 January 1983 if both of the following apply:
you were a citizen of the UK and Colonies (CUKC) on 31 December 1982
you had the ‘right of abode’ in the UK
This includes people who were born in a British colony and had the ‘right of abode’ in the UK.
It also includes people who:
were born in the UK
have been naturalised in the UK
had registered as a citizen of the UK and Colonies (CUKC)
could prove legitimate descent from a father to whom one of these applies
‘Right of abode’ means you:
are entirely free from UK Immigration Control and don’t need permission from an Immigration Officer to enter the UK
can live and work in the UK without restriction
If you were born in the UK on or after 1 January 1983
You don’t automatically get British citizenship if you were born in the UK.
If you were born in the UK on or after 1 January 1983, you’ll be a British citizen if your mother or father was either:
a British citizen when you were born
‘settled’ in the UK when you were born
‘Settled’ means you can stay in the UK without any time restrictions. This includes people who have one of the following:
‘right of abode’
‘indefinite leave to remain’
permanent residence as an European Economic Area (EEA) national
In most cases you’ll be a British citizen if your mother or father was born in the UK or naturalised there at the time of your birth.
If you were born before July 2006, your father’s British nationality will normally only pass to you if he was married to your mother at the time of your birth.
