The right of abode (ROA) is an immigration status in the United Kingdom that gives a person the right to enter and live in the UK. It was introduced by the Immigration Act 1971 which went into effect on 1 January 1973. This status is held by British citizens, certain British subjects, as well as certain Commonwealth citizens with specific connections to the UK before 1983. Since 1983, it is not possible for a person to acquire this status without being a British citizen.
