I'm currently employed and living in Germany. I have a Daueraufenthalt-EU card, whose validity ("kartennutzung bis DDMM2024") is tied to my US passport which expires in 2024.
What documents or proof are needed when a new card needs to be issued against the new passport?
I am exploring the possibility of a sabbatical or early retirement, which means I will not be able to show any payslips or letter from the employer. However, my residence will remain in Germany and I will cover my living expenses as well as my German private health insurance.
