A Singapore visa is not an immigration pass. It is a pre-entry permission for the holder of a valid Singapore visa to travel to, and seek entry, into Singapore. The grant of an immigration pass will be determined by the ICA (Immigration & Checkpoint Authority) officers at the point of entry.

Issued visa allows single or multiple entry into the country during its period of validity that depends on the passport holder type . This begins from the date of issue of the visa. Please bear in mind that the duration of each stay in Singapore cannot exceed 30 days, i.e. every time you are entering the country your passport will be accordingly stamped allowing to remain for (usually) 30 days.

Each entry to Singapore, passport will be stamped with a Visit Pass stating the date of the end of your permitted stay in Singapore for 30 days (most cases), after which you must leave the country.
