If Singapore visa is refused, what is the success rate of the appeal?

If ICA explicitly requests additional information, the chances of successful appeal are very high.

However, you don't have to book air tickets so early in the future. Applying for a visa in Singapore, 100% will not be approved. Your ticket may be invalid at any time.

The netizens upstairs don't know what an appeal is. Appeals are usually filed immediately after rejection, rather than waiting for three months.
