Mohammed Asif, of Oldham, helped 11 people get passports by claiming they were the children of the two men, British citizens of Pakistani heritage.
The 34-year-old, originally from Pakistan, was one of 10 people convicted for their roles in the scam after a six year Home Office investigation.
They include corrupt immigration advisor Shareen Akhtar, of Rochdale, who assisted with the applications and provided countersignatures.
Asif, said to be the ‘driving force’ behind the scam, stole the men’s naturalisation papers and other ID documents after telling the deceased men’s families he was an immigration advisior.
Asif, 34, of Abbeyhills Road, who was jailed for four years years and nine months, obtained his own British passport using the same method in 2010.
