SINGAPORE - Permanent residency (PR) in Singapore can be rescinded at any time should persons holding the status be found a security threat or have criminal records.
The case of former tour guide Yang Yin, who was found guilty of misappropriating $1.1 million from a Singaporean widow, has thrust the strict guidelines of PR eligibility into the limelight.
The Straits Times reported on Friday (Feb 17) that Yang's PR status was revoked in November last year.
Here's a look at three other cases that made the headlines:
1. Hartawan Aluwi
Indonesian banker Hartawan Aluwi had his PR status revoked in Feb last year after he was arrested for fraud.
Hartawan had fled Indonesia after he was listed as a suspect for allegedly misusing the government's money amounting to $685.5 million. He, along with several others, had wanted to bail out the now-defunct Bank Century during the 2008 global financial crisis.
Minister K Shanmugam had considered Hartawan to be "an undesirable immigrant ... due to his involvement in fraudulent investment schemes and money laundering activities", the Ministry of Home Affairs said.
On April 21, 2016, Immigration and Checkpoints Authority (ICA) took Hartawan into custody after the authority "declared his presence in Singapore to be unlawful."
2. Tey Tsun Hang
Former law professor Tey Tsun Hang was embroiled in a high-profile sex-for-benefits case with a student in 2013.
He was accused of obtaining sex and gifts in return for giving out good grades. Tey has since been cleared of corruption after serving a 5-months sentence.
The Malaysian had been a PR since 1998, but had failed in his bid to renew it as he had left the country without a re-entry permit.
The court noted that Immigration and Checkpoints Authority (ICA) officers did remind Tey of such a consequence, but the latter had still failed to apply for an extension despite agreeing to do so.
Tey's PR status was revoked in 2014.
3. Ryan Goh Yew Hock
In 2004, former Singapore Airlines (SIA) pilot Ryan Goh Yew Hock was singled out as the instigator behind the ouster of the executive committee of the Air Line Pilots Association-Singapore (Alpa-S).
Although Goh had reportedly crafted a petition to oust the then union leader Captain Dilip Padbidri and other council members, he did not sign it himself.
The Malaysian citizen was also found to have obtained permanent residency in Australia in 2002. He had relocated his family to Perth in 2003.
In view of these developments, Mr Lee Kuan Yew said in a statement to the media in 2004 that Goh had used his Singapore permanent residency status to obtain the benefits of a job, HDB housing and union Exco membership.
However, Mr Lee added: "That did not restrain him from surreptitiously initiating actions that would undermine industrial peace in SIA and also put Singapore's economic interests at risk."
Goh was a PR since 1981, a status which was later revoked in 2004.
