Mona el-Mazboh was arrested at Cairo airport at the end of her stay in late May in Egypt after a 10-minute video in which she called Egypt a “son of a bitch country” went viral on social media.
She was sentenced to eight years in prison in July after being found guilty of spreading false rumours that would harm society, attacking religion, and public indecency.
Her sentence was reduced earlier this week to one year and suspended.
Mazboh left Cairo by plane late on Thursday, her lawyer Emad Kamal said.
In the video, 24-year-old Mazbohcomplained of being sexually harassed by taxi drivers and young men in the street, as well as poor restaurant service during the holy month of Ramadan and an incident in which money was stolen from her during a previous stay.
