Man fined $2,400 for failing to show Singapore passport at immigration checkpoints

Teo also presented his Australian passport when he arrived at the immigration clearance at the Singapore Cruise Centre on Sept 4, 2008.

He was arrested on Oct 17, 2025 by Immigration & Checkpoints Authority (ICA) officers. Court documents did not state where he was arrested.

Teo, who was unrepresented, asked the judge for leniency in mitigation, citing his medical issues that require him to visit the optometrist every two months.

In response, the ICA prosecutor highlighted that Teo committed the offence out of convenience, and that he had exploited his access to both countries.

Responding to queries from The Straits Times, an ICA spokesperson said that Singapore does not allow its adult citizens to hold dual citizenship.

“ICA will investigate cases of suspected dual citizenship.

“Singapore citizens who are found to have obtained foreign citizenship or exercised the rights of a foreign citizen may be deprived of their Singapore citizenship, or be required to give up their foreign citizenship if they wish to retain their Singapore citizenship.”

Teo has since paid the fine in full.

For failing to produce a valid passport when entering or leaving Singapore, an offender can be fined up to $1,000, jailed for six months, or both.
