Individuals claiming asylum on the basis of sexual orientation or gender identity (SOGI) in Europe must prove to the authorities in question that they are ‘credible’ and meet the Refugee Convention criteria. In most cases, they do this by demonstrating that they belong to a Particular Social Group (PSG). However, for some time advocates and researchers have argued that SOGI claimants are treated both unfairly and inconsistently. In this article we use queer and intersectional theories to argue that one explanation for this how PSG membership has come to be interpreted. Looking at recent experience in two EU countries – Germany and the UK – we argue that this is done in a way that is both prescriptive, in requiring claimants to conform to minimal understandings of sexual and gender identity, but also narrow and one-dimensional, in ignoring other aspects of the claimant’s identity and assuming that SOGI asylum seekers are only sexual or gendered beings.
