Getting In
Singapore is one of Southeast Asia's largest aviation hubs, so unless you're coming from Peninsular Malaysia or Batam/Bintan in Indonesia, the easiest way to enter Singapore is by air. In addition to flag-carrier Singapore Airlines and its regional subsidiary SilkAir, Singapore is also home to low-cost carriers Tiger Airways, Jetstar Asia and Scoot.
Visa
Most nationalities can enter Singapore without a visa. Refer to the Immigration and Checkpoints Authority website for current guidelines, including a list of the 30+ nationalities that are required to obtain a visa in advance.
Customs
Please note that Singapore has very strict drug laws, and drug trafficking carries very severe sentences — which are applied to everyone, including foreigners. Singapore also does not have any duty-free concession for Liquor Products, Cigarettes and other Tobacco Products. Refer to the Customs website for more information on what you can bring in.
