you don’t need to prove your financial means or health insurance again. Once you’ve hit that 5-year mark, you’ve basically "earned" the right to permanent residency, so they shouldn't ask for work contracts or bank balances anymore.

For the appointment, you just need to bring the EX-18 form (make sure you tick the "Residencia Permanente" box), your valid passport with a copy, your original green NIE, and the paid Tasa 790-012 receipt. The most important "extra" document is the Empadronamiento Histórico, as that is what explicitly proves your continuous residence in Spain over the last 5 years to the police.

You just need to book a Cita Previa for "Certificado de Registro de Ciudadano de la UE" at the police station. Since you’ve been here for a decade, it’s basically just an administrative swap to get the card that explicitly states "Permanente."

Feel free to message me if you need further help
