Home Office: Immigration Branch: AIB, IB and IBR (Symbol Series) Files

HO 355

1921-1983

Files from the Home Office AIB (Aliens Immigration Branch) and IBR (Immigration Branch) symbol series.

The subjects covered in the AIB and IBR series relate to immigration control at sea ports and airports in the United Kingdom, and enforcement of the regulations originally defined by the Aliens Restriction Act 1914 and subsequently by the Commonwealth Immigrants Act 1962 and the Immigration Act 1971. These matters were, until 1962, the responsibility of the Immigration Branch of the Aliens Department of the Home Office. This branch and its functions were then transferred to the newly formed Immigration and Nationality Department.

Before 1949 some files on immigration topics were registered under an SI (Suspect Index) number and were re-registered in 1949 under an AIB number. The IBR series originated in 1963, following the Commonwealth Immigrants Act, and continued in parallel with the AIB series until 1971 when both symbols were replaced by the IB (Immigration Branch) series.

In numerical order by departmental file number. The inclusion of a date after a file number (as in 1/3/3(60)) indicates the year in which the file is supposed to have been created, but often it only indicates the year in which the first subfile was raised on a particular subject.
