An estimated 48,000 immigrants may have fraudulently obtained English language certificates despite being unable to speak English, the government has said.
Immigration Minister James Brokenshire told the Commons that an inquiry into abuse of the student visa system had found evidence of criminal activity, which would now be investigated fully.
Mr Brokenshire continued: "It is likely that the true totals will be higher."
"The government is not prepared to tolerate this abuse," he said.
The minister said the tax department has identified a number of overseas university students earning more than £20,000 a year despite the rule that they must not work more than twenty hours per week during term time.
