This guide is the rebranded edition of the COI Reserach Guide on LGBTIQ 2021. This COI Research Guide focused primarily on sexual orientation (LGB persons) and not on gender identity, gender expression and sex characteristics (transgender and intersex persons). The guide should serve the needs of both experienced and inexperienced COI researchers , as well as caseworkers conducting COI research on the situation of LGBTIQ people. Additionally, it may assist lawyers, legal aid providers and judges working in the asylum procedure.
