Nationals from a wide majority of countries do not require visa for social visits of a 30-day duration provided they are in possession of recognised and valid travel documents, adequate funds and return or onward tickets. For a list of countries which will require a visa to enter Singapore, please visit Singapore Immigration & Checkpoints Authority website:
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 Immigration & Checkpoints Authority (ICA) officers at the point of entry. Possession of a valid visa alone does not guarantee entry into Singapore.
A holder of a valid Singapore visa who is found suitable for entry into Singapore will be issued with an immigration pass to enter and remain in Singapore. You are advised to check your passport for the arrival visit pass endorsement when in Singapore and take note of the period of stay granted before leaving the checkpoint.The period of stay granted is shown on the visit pass endorsement given on your passport and it is not tied to the validity of your visa.
