Renewing early costs nothing. The new work pass validity is not reduced, and any remaining validity from the current pass, up to six months, is added on. MOM states that a renewal application is processed or given an update within 10 business days, and that a Dependant’s Pass renewal is processed within 3 weeks for most cases. For a Dependant’s Pass, the renewed pass duration starts when the current pass expires.
Renewing late is a different situation. If the deadline is missed, a new pass must be applied for rather than a renewal. The pass must be issued before the In-Principle Approval or the current pass expires, whichever occurs first.
A Short-Term Visit Pass can be requested to give the pass holder valid stay in Singapore while matters are resolved. It can be requested on cancellation, or within a day after the EP expiry date, and it grants valid stay of up to 90 days.
