I am an Indian citizen and I have a flight to Japan with a 7 hour layover at Singapore. I only have a temporary visitor visa for Japan. I was wondering if I could go out of the airport and visit Singapore, and what additional procedures(if any) I might require for that?
As stated by Timatic, the database used by airlines:
Visa required, except for Nationals of India who can also transit, for up to 96 hours without a visa under the Visa Free Transit Facility (VFTF) on either the outbound or return leg of the same journey (but not on both). Leaving the transit area is allowed.
Warning: Holders of a valid single entry visa (or multiple entry visa valid for at least one month) issued by Australia, Canada, Germany, Japan, New Zealand, Switzerland, USA or United Kingdom to nationals of India may use the VFTF mentioned above. After using a single entry visa and the VFTF was not used on the outbound leg of the journey, the VFTF can only be used on the return leg with a direct transit through Singapore from the country that issued the visa to the country of residence (e.g., SYD-SIN-PEK).
So yes, you can visit Singapore. Present your passport open at the page with the Japanese visa, and your connecting ticket.
Indian nationals who are in transit to or from any third country by air, may be eligible for the 96-hour VFTF for one transit in the itinerary (either forward or return leg, but not both) if they: i. have a valid onward air ticket departing within the next 96-hours; and ii. possess a valid visa/long-term pass (with a validity of at least 1 month from the date of entry into Singapore under the VFTF) issued by any of the following countries**: a. Australia b. Canada c. Japan d. New Zealand e. United Kingdom f. United States of America g. Germany h. Switzerland ** A visa is considered valid if it is not expired and is good for entry into the third country. ** The VFTF for Indian nationals is for air to air travel only, and is only valid for one transit in the itinerary (either forward or return leg, but not both).
