Singer Amy Winehouse has met officials at the US Embassy in London to discuss obtaining a visa.
Winehouse's hits include Back To Black and Rehab
Winehouse, who checked into rehab at the Capio Nightingale clinic in north London last month, was accompanied by her father Mitch and a nurse.
The 24-year-old is due to perform at the Grammy ceremony, where she is nominated for six awards, in Los Angeles on Sunday.
But her spokesman said "no decision" had been made about the appearance.
"The appointment at the US Embassy was made some time ago and was part of process for obtaining a visa," he said.
"Amy was accompanied by a nurse as the appointment was under supervision. She has not left rehab and remains under the care of the clinic."
Winehouse was admitted to the Capio Nightingale clinic in north London on 24 January, days after a video emerged that apparently showed her smoking a crack pipe.
Attending the US Embassy, she looked healthier than in recent weeks, dressed in a white skirt and polka dot top and sporting her trademark beehive hairdo.
Her application for a visa will not be simple due to her drugs record - last October she was arrested and fined in Norway for possession of cannabis.
She is planning to appeal against the fine in a Norwegian court later this month.
Winehouse's Grammy nominations include record, album and song of the year.
