Nationals of the Commonwealth Independent States may be granted entry into Singapore without visas if they are on transit to a third country. However, they are required to fulfil the following conditions:-
They are in transit to a third country;
They hold a valid passport, a confirmed onward air-ticket, entry facilities (including visa) to the third country and have sufficient funds for the period of stay in Singapore;
They continue their journey to the third country within the 96-hour visa free period granted; and
They satisfy Singapore's entry requirements. As in all arrivals, the grant of the social visit passes to travellers will be determined by the Immigration & Checkpoints Authority officers at the Singapore Checkpoints.
