Can I transfer my existing REP to my new passport with the new nationality/citizenship acquired?

If you have acquired a new nationality, you will have to update the details of your new nationality/citizenship in your Identity Card (IC) using ICA e-Service before submitting a REP application.

Thereafter, you can book two same-day appointments using e-Appointment to:
(1) collect your IC at the Citizen Services Centre, Level 3 and;
(2) submit an REP application at Permanent Resident Services Centre, Level 5, under your new nationality.

You are required to bring your completed application form and supporting documents, on the day of your appointments.
If you are below 15 years of age and do not possess an IC, please book an appointment to update your new nationality together with supporting documents and submit a REP application at Permanent Resident Services Centre, Level 5.
