"Citizenship By Parentage Under British Law
As we indicated above, the citizenship by birth (jus soli) requirement derived from Britain in 1608. But in 1981, the British abandoned the age-old citizenship by birth (Jus soli) and adopted the parentage-based citizenship law. Under their parentage-based citizenship, a child born to one or two British parents is a British citizen, regardless of where the person was born. Under the British parentage-based citizenship Law, the person�s place of birth no longer determines his citizenship. For example, if the person was born anywhere in the United Kingdom to one or two parents who are not British citizens, that person is not entitled to British citizenship. But if the person is born to one or two British parents in Britain or elsewhere in the world, he is a British citizen."
