is it possible for me to apply and get my visa within one day? How much fees I need to pay for?

Tan, it's not possible to get it within one day. If you use the urgent service, it will take two working days to get it. The fee for a single entry type is 65 Singaporean dollars if using regular application service, 120 for express service, and 155 for urgent service.

You need to bring your passport, a photocopy of the passport's data page, a filled-out application form attached with your recent color bare-headed photo, the original and photocopy of your residence permit in Singapore, and round-trip tickets and hotel reservations for the trip.
