I have a multiple-entry visa for Singapore, valid for 2 years. The visa was issued on 20th Nov 2014, and remains valid until 21st November 2016. I have made only one trip, in December 2014.
Do I need to provide any additional documents before I attempt visit Singapore again, using the same visa, in December 2015?
Do I need to produce any more documents than return tickets for getting the immigration pass?
