If your passport has expired, you can continue to reside in Singapore as a permanent resident (PR), but you will not be able to travel. Hence, it is advisable for you to obtain a new passport as soon as possible and thereafter apply to renew your re-entry permit (REP) or transfer your valid REP online. A PR will lose his PR status if he travels out of Singapore without a valid REP.

Please note that a passport must have at least 3 months validity in order to make an REP application online via the e-Service.
