Theresa May's leaked letter about family-route visas for non-EU nationals holds valuable insights into the motivations of the government. May proposes upping the minimum income level to £25,700 (£50k if you have two children) and increasing probationary visas from two to five years. At the moment, family-visa applicants must show  they have enough income to cover essential bills; most submit a budget to reflect their individual circumstances. This is to prevent migrants from relying on the state; what critics of family immigration don't realise is that most of us can't receive benefits.
