Troubled singer Amy Winehouse was temporarily released from rehab on Monday--to apply for a U.S. visa.
The "Back to Black" hitmaker left the London clinic for just a few hours to meet officials at the U.S Embassy.
She was accompanied by her father, Mitch, and a nurse, as the terms of her treatment say she must remain under supervision at all times.
It is believed Winehouse is applying for a visa to attend the Grammys in Los Angeles ..
