Singapore’s Immigration Act specifies that persons overstaying their visas or equivalent permits are liable for judicial caning if they overstay by more than 90 days. There are exceptions pertaining to age. Women are also not caned.
Unlawful entry or presence in Singapore

in the case where he remains unlawfully for a period not exceeding 90 days, shall be liable on conviction to a fine not exceeding $4,000 or to imprisonment for a term not exceeding 6 months or to both;
in the case where he remains unlawfully for a period exceeding 90 days, shall on conviction be punished with imprisonment for a term not exceeding 6 months and shall also, subject to sections 325(1) and 330(1) of the Criminal Procedure Code 2010, be punished with caning with not less than 3 strokes, or where by virtue of that section he is not punishable with caning, he shall, in lieu of caning, be punished with a fine not exceeding $6,000.
