A twitter contact of mine has started a gofundme campaign to help a Tunisian friend come to the US. As the campaign explains:
"M is a queer 20 year old Tunisian woman, who is studying computer science. She dreams of becoming a forensic scientist but currently is facing threats against her life for looking (and being) gay. Being homosexual is currently an offense punishable by jail time in Tunisia, though gay Tunisians often face life threatening violence and harassment. M has had threats against her life, classmates promising to beat her, etc., but she cannot afford the costs to come to the US."
For more information or to donate, see the campaign:
