The association posted guidance on the ten-year renewal procedure for permanent residents. Permanent residence status itself does not expire, but the alien registration card must be reissued every ten years.

Applications must be filed before the expiry date and require a passport, the current registration card, a photograph and a fee. They may be made in person at the competent immigration office or through the online civil affairs portal.

Missing the deadline may draw a fine. Permanent residence is not lost immediately, but an expired card creates verification problems in everyday matters such as banking, property contracts and health insurance.

Many permanent residents among Korea's overseas Chinese obtained the status long ago. Cases of people missing the point at which the ten years since first issuance elapse have been reported repeatedly.

The association urged families of older members to check expiry dates together. Where postal notices are not received, or a change of address has not been registered, no notification arrives at all.

Those who have moved must file a change of residence for foreign nationals separately from the domestic move-in report. If this is omitted, notices - including renewal reminders - go to the previous address.
