The three-time Wimbledon champion was jailed last month for two and a half years.
Boris Becker could be facing deportation at the end of his sentence after he was reportedly moved to a prison holding foreign criminals.
The 54-year-old is in prison for hiding £2.5 million of assets and loans to avoid paying his debts.
