How long can the Singapore visa be renewed?

The tourist visa can stay for up to 30 days, and can be renewed once for free, and the stay period can be extended for 30 days. You can also choose to pay a renewal fee, which costs more than S $10 and you can stay for another 90 days. The latter is not easy to be approved.

In other words, most people can basically stay for 60 days at a time.

You need to go through the renewal formalities at the immigration office in Rivenda one week in advance. You can get there directly by subway. Go straight to the service desk in the lobby and wait in line. The staff will help you.
