Apart from visitors from China and India, most foreigners coming into Singapore do not require visas for entry and may be given up to 30-day social visit passes upon their arrival in Singapore. However, it is best to consult your local consular office for the latest information with regards to coming into Singapore.
If you would like to stay in Singapore for a longer period, you may apply at the Immigration & Checkpoints Authority (ICA) upon your arrival. However, you should have your valid passports, onward or return tickets, onward facilities (such as visas or entry permits) to your next destination and of course, sufficient funds for your stay in Singapore.
Should you lose your passport while in Singapore, please make a police report immediately, then head to the ICA (right across from the Lavender MRT Station at 10 Kallang Road) to get a temporary visa. Finally, inform your respective embassy so that you can get through immigration when you reach home.
Women in an advanced state of pregnancy (six months or more) who intend to visit Singapore should make a prior application with the nearest Singapore overseas mission.
