US immigration authorities have removed radio tags from the ankles of two Indian students from California-based Tri Valley University. The Consul General, Indian Consulate San Francisco Susmita Gongulee Thomas said that Immigration attorney, Kalpana Peddibhotla had taken two of the students to Immigration and Customs Enforcement (ICE) office and she has been able to obtain the removal of the radio tags from them. Thomas said that some more students will be taken to the ICE office next week and expressed optimism that this might have positive outcome as well. Peddibhotla and these students had attended a free legal aid camp organised by the Indian Consulate in San Francisco in association with the South Asian Bar Association.According to a federal complaint filed in a California court in January, the University helped foreign nationals illegally acquire immigration status. The university is said to have 1,555 students. As many as 95 per cent of these students are Indian nationals, the complaint said. Investigations by ICE have found that while students were admitted to various residential and on-line courses of the university and on paper lived in California, but in reality they illegally worked in various parts of the country as far as Maryland, Virginia, Pennsylvania and Texas. ICE has called it as a Sham University, a charge denied by the University. 18 students in California were radio-tagged by ICE as part of their investigation against Tri Valley University. Ankle monitors send a radio frequency signal containing location and other information to a receiver.
