An Exit Permit Only (EPO) is the official departure clearance required when you leave Indonesia for good and won't be renewing your E33G visa/KITAS. Without an EPO, you may run into complications with a future re-entry or a new visa application.
You typically need an EPO when you let your KITAS expire and leave Indonesia permanently, or when you leave the country for good before your visa expires and don't plan to re-enter on this permit.
If you plan to return later with a new E33G, reach out to us in advance — we'll help you check whether and when an EPO is required in your case.
