Can a tourist visa from Singapore work in Singapore?

In order to crack down on illegal immigration crimes, Singapore has enacted strict laws and punishment measures, which are severe and ruthless. If it is a male, it will be whipped, more than four lashes, but not more than six lashes! If it's a woman, it's free from whipping! Specific circumstances of seeking punishment (depending on the court's determination):

1, illegal immigrants shall be sentenced to fixed-term imprisonment of not less than three months but not more than two years, with more than three lashes, recidivists shall be sentenced to fixed-term imprisonment of not less than one year but not more than three years, and a fine of S $6,000 shall be imposed.

2. Illegal residents will be punished with different criminal responsibilities according to their illegal residence time:

(1) If the illegal detention time is less than 90 days, a fine of less than S $4,000 or imprisonment of less than 6 months may be imposed, and if the circumstances are serious, it may also be imposed;

(2) The bright spot is coming. Those who illegally stay for more than 90 days shall be sentenced to imprisonment of not more than 6 months, flogging of not less than 3 lashes (or a fine of not more than S $6,000);

(3) Illegal prostitution (aggravated by illegal work) involving illegal detention will be punished as illegal detention.

(4) After serving his sentence, he was immediately escorted to the airport and deported, and was forbidden to enter Singapore for life.
