What happens to my Norwegian social security membership and health coverage when I move?

Membership in folketrygden normally ends when you emigrate — and with it, Norwegian health coverage. As a resident of Portugal you enter the Portuguese system (SNS), and EEA coordination preserves accrued pension rights, which aggregate across both countries. The traps: voluntary Norwegian membership must be applied for BEFORE you leave if you want it, disability benefits have their own export rules, and stays over 12 months without planning can end membership automatically. Sort this in the same project plan as the tax exit — not after arrival.
