If your REP has not expired, you may submit another REP application online at ICA e-Service for consideration, by declaring and stating your reasons in the free-text box. If necessary, the processing officer will request for documents and you do not have to write to us separately.
Similarly, if you have lost your PR status and wish to appeal, you may submit a reinstatement application online using the same e-Service for ICA's consideration. Should you have any fresh grounds for ICA to review, please indicate them in your application.
