Hundreds of students from Sri Lanka could be here illegally, while officials do what they can to investigate claims of a major scam involving student visa applications from Sri Lanka.

The New Zealand immigration office in Mumbai that handles Sri Lankan applications received a tip off at the start of the year.
Inquiries led officials to conclude a Sri Lankan based finance company was fraudulently creating documentation to help students meet the criteria of having $15,000 in the bank.
Official briefings to Immigration Minister Iain Lees-Galloway show investigations are under way into the potential involvement of education agents in Sri Lanka, the finance company, whose name is redacted in the papers, and students as a result of these revelations.
There were 88 pending applications when the fraud was discovered and after further checks were done 83 were declined. The tip-off was in January.
Immigration Minister Iain-Lees Galloway said officials did not yet know how many fraudulent applications may have slipped through the net.
There could potentially be hundreds of students here illegally, Mr Lees-Galloway said.
"So what Immigration New Zealand is doing is identifying the ones that have the potential to be fraudulent and I think are taking sensible action."
However, he said officials were somewhat hamstrung in their ability to establish the authenticity of thousands of past applications.
They were going through 895 applications that came from Sri Lanka through the Mumbai office, to identify which ones contained information from the "fraudulent" finance company, the minister said.
"And they would place a flag against those applications, those people still in New Zealand, in the event that they try to extend their visa and stay in New Zealand longer, closer scrutiny would be applied to those applications."
The New Zealand government would not, however, be challenging any visas other than the original 88 when the fraud was discovered, Mr Lees-Galloway said.
"The challenge that Immigration New Zealand faces with trying to do this retrospectively is they rely on the finance company to provide the bona fide information when they're assessing an application," he said.
"Given this finance company has proved to be fraudulent it's a pointless exercise for Immigration New Zealand to go back to them and ask them to verify the information that they gave in the first place."
Immigration New Zealand no longer dealt with that company, he said.

Acting Prime Minister Winston Peters said he and the New Zealand public expected the immigration system to be robust, and for the minister and officials to uphold those expectations.
But he accepted there could be significant numbers involved in this scam.
"I've go no doubt that is possible, but our job is to make sure it stops and we tidy up the processes."
Meanwhile, the National Party wants to know why hundreds of past visas that have been granted to Sri Lankan students won't be reviewed.
The papers said a number of New Zealand educational providers had been affected and they had been told about what had happened and warned about the impact of student numbers in the future.
There was also an allegation "students paid an additional fee to secure the documentation" which was under further investigation.
From 2015 to 2017 there were about 5000 student visa applications from Sri Lanka of which about 3800 were approved. The documents do not make it clear how long officials think the scam has been going on.
Former Immigration Minister and National Party spokesperson Michael Woodhouse asked Mr Lees-Galloway whether he would look at past years to make sure the visas approved were legitimate.
Mr Lees-Galloway said that after scrutinising, then rejecting, most of the 88 applications the focus would now be on any future signs of fraud.
"To identify applications with similar characteristics already decided by INZ [Immigration New Zealand] would require substantial collation which I do not believe is in the public interest."
According to Mr Woodhouse, up to half of Sri Lankan applicants could have used the company "fraudulently", and said that should be enough for officials to find how widespread any fraud was.
They were arriving in New Zealand ripe for exploitation as they had no money to support themselves, he said.
"I'm concerned that they are perpetrators but also potential victims."
It was "extraordinary" that the minister admitted no work had been done to review past applications.
"Of course it's in the public interest to make sure our visa system has integrity."
