Nine months in prison for forged paperwork.
Charles Ngereza, of Tower Road, Erdington, had demanded pounds 20,000 to leave Britain voluntarily when he was questioned by border agency officers, Warwick Crown Court heard.
The 39-year-old father of two pleaded guilty to obtaining leave to remain here by deception and assisting unlawful immigration. Prosecutor Nigel Wilkins said Ngereza came to the UK on a student visa in 2003.
A year later he applied for leave to remain on ancestry grounds, claiming that his grandfather was a British national and provided birth and marriage certificates which were accepted.
But on returning to Britain after a trip abroad in July last year he was stopped by border agency officers who became suspicious when he was unable to go into detail.
