Your need for a Singapore Visit Visa is based on your citizenship. People from many countries, like the U.S., UK, Australia, and much of Europe, do not need a visa for stays up to 30 days. But if you are from a country that requires a visa, such as India, China, or Nigeria, you'll need to apply for a Short-Term Visit Pass (STVP) before you arrive. This pass is for tourism, social visits, or business, but not for work. Always check the Singapore Immigration & Checkpoints Authority (ICA) website for the most current entry rules related to your passport.
