US has cautioned Indian students, who are planning to come to America, to be alert to the existence of predatory visa fraud rings and fraudulent document vendors.
The statement gains significance in the wake of raid on yet another US university on the alleged charges of visa fraud.
"We caution them to be alert to the existence of these so-called predatory visa fraud rings and fraudulent document vendors," State Department spokesman Mark Toner told reporters at his daily news conference.
Toner said the US is looking into the issue of raid by federal authorities at University of Northern Virginia (UNVA).
"We are following the case closely, and we're in communication with the Government of India officials on it," he said.
Embassy New Delhi has briefed the Ministry of External Affairs as well and the US Department of Homeland Security and the State Department have been in contact with the Indian Embassy here, he said.
"This is an investigation that's ongoing, so I'm limited in what I can give in terms of details. But it's important to note that a hundred thousand Indians are receiving a good education at certified US institutions each year, and we certainly welcome the contribution of Indian students wishing to study in the United States," Toner said.
