Daniel Northover left his home in Liverpool this month, which marks the 10th anniversary of Britain¡¯s Brexit referendum, to move in with his 80-year-old mother in Turre, a town of 4,500 people in Andalusia in southern Spain.

After his stepfather died last summer, Northover, 53, has taken turns with his sister to travel back and forth to Spain to care for his mother, ?Carole, who cannot cook, clean or dress by herself after suffering several strokes.

But with non-EU residents only allowed to remain in ?the bloc for ?90 days in every 180 without a visa, he said it had become unsustainable. A project manager for ?local councils and charities, Northover did not meet the requirements for a working visa. Visas to care for a dependent family member are only available if it is the U.K. citizen needing the care.
