You don't need visa for stay upto 96 hours. Conditions are that your Japan/US visa must not be expiring in next one month. And the Japan visa should be multiple entry.Guys I am traveling form manila to delhi via singapore and have heard that singapore allows us to visit city for 4 days without Singapore visa if we have japan and us visa. Have anyone used this method in Singapore.
Met someone today who says u need visa and I checked internet days don't need visa
If you have single entry Japan visa then you can't enter Singapore on the return leg from Philippines. If you have multiple entry US/Japan visa then no problem.
