Cape Town specialist Professor Cyril Karabus may be home on Tuesday.
His legal team says it's met prosecutors in Abu Dhabi and the professor could get his passport back tomorrow and be cleared for travel.
The 78-year-old South African doctor has been held in the United Arab Emirates for eight months on a charge of manslaughter over the death of a young cancer patient in 2003.
On Wednesday, a second court in Abu Dhabi upheld an acquittal of the elderly doctor.
Prosecutors could now take the case to the highest court, the UAE's equivalent of the Constitutional Court, but this would be on a point of law and should not affect Professor Karabus personally.
