Two versions of the same idea, tuned for different time horizons. Both open from age 55 and both require the retiree to remain non-working while in Indonesia.

Foreign nationals aged 55 or older retiring to Indonesia on an annually renewed permit (E33F)
Foreign nationals aged 55 or older wanting five or ten years of residency in one grant (E33E)
Retirees whose income comes from pensions, investments, or savings held outside Indonesia
