On the day of the EU referendum, a British Remain campaigner told me: ‘I’m very glad you’re here.’ I know she meant well, but her words felt exclusionary as well as inclusive – I may be welcome, but I’m still foreign. In recent years there have been increasing restrictions on who can move or settle here from outside the EU – from eliminating the post-study work visa to requiring an annual income of at least £35,000. And the person who oversaw these restrictions as home secretary is now our prime minister.
