Diana left her native Peru two years ago, looking for financial and professional stability in Europe.

"Working without residency documents is hard because employers can tell you one thing and then get you to do something else," she says. "Sometimes they pay you less than what you've agreed to, so that makes things tough.

Access to many banking products and housing – which is seeing a crisis in Spain due to spiralling rental costs – is severely restricted for those unable to present residency papers to potential landlords.
