A mother and son from Birmingham have admitted arranging a string of "sham" marriages.
Patricia Williams, 60, and her son, Jason Williams, 38, of St John's Road, Dudley, pleaded guilty to breaching immigration laws when they appeared before Birmingham Crown Court.
The pair will be sentenced together on September 4.
The Williams family have been prosecuted for arranging bogus weddings to foreign nationals from Africa and Jamaica before.
Last month, eight other people, seven of whom were related to the defendants, were sentenced.
The criminal mastermind behind the scam was Vendrick Clarke, 51. He was sentenced in August last year to nine years in prison for conspiracy to defraud the Home Office, conspiracy to facilitate a breach of immigration laws and one count of supplying Class A drugs.
