British National (Overseas), commonly known as BN(O), is one of the major classes of British nationality under British nationality law. Holders of this nationality are British nationals and Commonwealth citizens, but not British citizens. The nationality itself does not grant right of abode anywhere in the world, including United Kingdom or Hong Kong, but all BN(O)s are permanent residents of Hong Kong. BN(O)s are subject to British immigration controls and do not have the automatic right to live or work in the United Kingdom.
