The U.S. visa status of former Anglo Irish Bank president David Drumm is being challenged by his old bank as they seek his return to Ireland.

The bank wants to question him about many of the loans which led to the Irish government having to commit to repay up to $40 billion dollars worth of bad loans.

The bank is owed $8.5 million by Drumm,who is living near Boston and recently claimed bankruptcy in an American court.

Anglo-Irish filed papers in the US courts on Thursday, saying Drumm is no longer eligible for the E-2 visa he currently holds.

Anglo-Irish want to question him about all his financial dealings while in the U.S. and also some deals he struck while in Ireland.
