At least 1,500 foreign students, including six from India, who entered Malaysia to study, have now "disappeared".
The students, who have not registered with any institution and thus disappeared, had abused the conditions of students pass and the government was working to stop this through more stringent checks and tighter requirements, Deputy Home Affairs Minister Tan Chai Ho said.
"There are foreign students who use their student passes to enter the country to work, not to study," the Star newspaper quoted him telling reporters here.
"We have been informed that about 1,500 who came to study have not registered with any institution."
Citing a case, Immigration Department head of enforcement Ishak Mohamad said 380 foreign students from a private college in Seremban would attend a few classes at the start of their term and then disappear.
They came back again to collect their certificates at the end of the course signifying that they had successfully completed their education.
Ishak said this was the modus operandi of the college that was under investigation.
Of the 380 missing students, 260 are Bangladeshis, 70 Pakistanis, 25 Nigerians, 13 Sri Lankans, six Indians, five Chinese nationals and one Filipino.
