Final Departure or EPO (Exit Permit Only)
When you are reading to leave Indonesia for good you will need to turn in your KITAS, Buku Pengawasan Orang Asing and obtain an 'exit only' permit from the immigration office. After getting the EPO stamped on your passport, a copy of the stamp is needed to apply for cancellation on your SKPPS, SKLD, Work Permit. You must turn in the original documents to each department who issued the permits.
