I am an Indian citizen on a one year multiple entry visitor's visa to Singapore. I am visiting relatives in Singapore. I plan to go to Surabaya for a week and re-enter Singapore for 3 weeks more with relatives before returning to India. My Air tickets are all confirmed. How do I get my re-entry visa when I come in from Surabaya?
A multiple-entry visa is just that, you can enter and exit multiple times, without needing additional re-entry permits. Singapore does not care where you go between visits.
