After acquiring Indefinite Leave to Remain, it is possible to apply for British citizenship by naturalisation after meeting normal residence requirements. See British nationality law
* The increase in the period of time under UK Ancestry to 5 years before ILR can be applied for effectively means that applicants (who are usually not married to British citizens) must wait 6 years for British citizenship. This is because naturalisation as a British citizen for a person not married to a British citizen requires that ILR or its equivalent be held for 12 months.
* Children born in the United Kingdom to persons with UK Ancestry (since 1983) are not British citizens by birth. However the child can be registered a British citizen once the parent obtains ILR if the child is still under 18 (it is not necessary to wait for the parent to become British).
