If you are planning a trip to Singapore and you need a visa, this article details the Singapore visa application. A Singapore visa allows the holder to enter a Singaporean point of entry, where they will be checked by the Immigration & Checkpoints Authority (ICA) officers. The ICA decide whether the visitor meets the requirements for entry into the country. You have to apply for a Singapore visa at least 30 days before you arrive in Singapore. But keep in mind that just because you have a Singapore visa, it does not mean you will be allowed to enter since the Singapore visa is just pre-entry permission. If you meet the entry requirements, however, you will receive a Pass which allows you to enter Singapore and stay for the duration that the Pass is issued. For example, for a Singapore tourist visa, you will receive a Visit Pass, usually valid for a maximum of 30 days within a 90-day period.
