Singapore provides a 96-hour visa-free transit facility [VFTF] to nationals of the Commonwealth of Independent States [CIS], India, Georgia, Ukraine, Turkmenistan, and the People’s Republic of China [PRC].
However, do note that certain conditions apply for assessing eligibility for the VFTF facility.
If their airlines do not have the requisite transfer capabilities, foreign travelers may be obliged to travel through Singapore Immigration. In these circumstances, the foreign tourist should apply for a visa ahead of time to avoid any problems when transiting through Singapore.
