Detroit, Michigan, which owes at least $ 15bn (£10bn), has become the largest US city to file for bankruptcy.
State-appointed emergency manager Kevyn Orr asked a federal judge for permission to place the city into bankruptcy protection.
If approved, he would be allowed to liquidate city assets to satisfy creditors and pensions.
Detroit stopped unsecured-debt payments last month to keep the city running as Mr Orr negotiated with creditors.
