There is a question in my permanent residence form:
Haben Sie Pflichtbeiträge zur gesetzlichen Rentenversicherung oder Aufwendungen auf vergleichbare Leistungen einer Versicherungs- oder Versorgungseinrichtung entrichtet?
Have you paid compulsory contributions to statutory pension insurance or expenses for comparable benefits from an insurance or pension scheme?
I didn't quite understand it. Can somebody can explain this? (I have a blue card and have been working at that job from the very first day.)
