E31C is the KITAS category for a foreign child of an Indonesian citizen (at least one parent is WNI/ Indonesian citizen).Through E31C, the child even if foreign can legally reside in Indonesia based on the “family reunification” with their Indonesian parent.
a. Having E31C doesn’t automatically mean full citizenship or permanent residency it’s a temporary stay permit (KITAS), usually 1–2 years with renewals.
b. While children may attend school or reside, additional rights (like working for wages, permanent residency, citizenship) depend on broader rules. E31C is focused on family-based stay/ KITAS, not citizenship or permanent immigration.
With this KITAS you can
✔ Live and study in Indonesia.
✔ Travel to and from Indonesia as many times as you want.
