Går min KITAS- eller KITAP-pension ut när jag lämnar landet?

No. The Pensionering KITAS och Pensionering KITAP are multiple-entry permits, meaning you can enter and leave Indonesia as often as you want during the validity period.

Your KITAS/KITAP will inte expire automatically just because you travel abroad.
It only expires on its official end date, unless cancelled intentionally (e.g., through an EPO).
